A car of weight 3,217 lb is traveling in a straight line at a speed of 60 ft/s. how much force does it require to stop the car in 5 seconds? assume that the gravitational acceleration is 32.17 ft/s2.

Answers

Answer 1

Answer:

in this problem, we have given a card of wait. £3217 is traveling in a straight line at a speed of 60 ft/s. How much force does it require to stop the car in five seconds. So here we will use a cinematic equation. We finally, is it caused to the initial plus acceleration in two times. So finally, spirit will be zero initially 60 ft/s and exhalation. We have to find And time is five seconds. Right? So we need acceleration, Which is a cost to -60 x five. That is a cost to 12 feet per second square. That means we need acceleration in the opposite direction, so we need a force which is in the opposing direction of the motion. So this force, if we talk about the magnitude, there should be equal to mass into acceleration. So this mass of card will be weight divided by G, into exploration. That is 12 serve it of cars, and 3217, And G is 32.17 in 212. So this force in pounds is equal to £1200 in the opposite direction of motion.

Explanation:

Answer 2

The force required to stop the car is 5334.09 Newtons. The force is negative representing the deceleration.

The car's weight to mass:

Weight = 3,217 lb

1 lb = 0.453592 kg

Mass = Weight ÷ gravitational acceleration

Mass = 3217 × 0.453592

Mass = 1459.59 kg

The initial velocity is:

Initial velocity = 60 × 0.3048

Initial velocity = 18.288 m/s

Since the car stops, the final velocity will be 0 m/s.

The acceleration is:

Acceleration = (Final velocity - Initial velocity) ÷ time

Acceleration  = -3.6576 m/s²

The force required to stop the car using Newton's second law of motion:

Force = m × a

Force = 1459.59 × (-3.6576)

Force = -5334.09 N

Therefore, The force required to stop the car is 5334.09 Newtons. The force is negative representing the deceleration.

A father and his young daughter are ice skating. they face each other at rest and push each other, moving in opposite directions. which one has the greater final speed? group of answer choices

Answers

A father and his young daughter are ice skating. According to it, the daughter has greater speed.

The law of action and response is Newton’s third principle.

According to Newton’s third law, when two bodies come into contact, they exert forces on one another that are equal in size and directed in the opposite direction. The law of action and reaction is another name for the third law.

This law applies to bodies in uniform or rapid motion and is crucial for addressing problems of static equilibrium, where all forces are in balance. The forces it discusses are actual phenomena, not just accounting tricks.

If there is a net force operating on a body, it moves faster in line with the second rule.

If there is no net force acting on the body, either because there are no forces at all or because all forces are precisely balanced by opposing forces, the body does not accelerate and is said to be in equilibrium.

On the other hand, it can be assumed that a body that appears to be moving slowly has no net force acting on it.

So going according to it, the daughter has greater speed.

What would happen to the predominant protonation state and charge of the his and asp side chains if the ph were to change from 7.40 to 5.00?

Answers

The predominant protonation state and charge of the His and Asp side chain will be predominantly protonated and positively charged if both its p[tex]K_{a}[/tex] values is more than 5.

We know that,

pH = p[tex]K_{a}[/tex] + ( log [ [tex]A^{-1}[/tex] ] / [ HA ] )

where,

[ [tex]A^{-1}[/tex] ] represents deprotonated form

[ HA ] represents protonated form

Consider pH = p[tex]K_{a}[/tex]

In this case,

[ [tex]A^{-1}[/tex] ] / [ HA ] = 1

This means that protonated and deprotonated forms are equal.

This also means that as pH decreases, the acid's state will be predominantly protonated and its charge will be positive.

The relationship between pH and p[tex]K_{a}[/tex] shown above is known as Henderson-Hasselbach equation

Therefore, the predominant protonation state and charge of the His and Asp side chain will be predominantly protonated and positively charged if both its p[tex]K_{a}[/tex] values is more than 5.

A boy sledding down a hill accelerates at 1.25 m/s2. if he started from rest, in what distance would he reach a speed of 5.30 m/s?

Answers

By uniform motion, the distance traveled is 11.24 meters.

We need to know about the uniform motion to solve this problem. The uniform motion is the motion of an object which has acceleration applied. It can be determined as

vt = vo + a . t

vt² = vo² + 2a . s

s = vo . t + 1/2 . a . t²

where vt is final velocity, vo is initial velocity, a is acceleration, t is time interval and s is displacement.

From the question above, we know that:

a = 1.25 m/s²

vo = 0 m/s

vt = 5.3 m/s

By using the second equation, we can calculate the distance

vt² = vo² + 2a . s

5.3² = 0² + 2 . 1.25 . s

2.5s = 28.09

s = 11.24 m

If the entire apparatus is immersed in water, what happens to the distance between the fringes on the screen?

Answers

The space between the screen fringes will be closed if the complete apparatus is submerged in water.

What does fringe distance mean?

The space between two consecutive bright spots (maximas, when constructive interference occurs), or two consecutive dark patches, is known as the fringe width (minimas, where destructive interference occurs). All of the fringes in Young's double-slit experiment are the same length. The formula yields the fringe width. β = λD/d. Because it depends on L, the spacings between various fringes get smaller as the slit distance gets bigger. Since the space between various fringes is wavelength dependent, increasing the light's wavelength also increases that separation.

In comparison to air, water has a shorter wavelength of light. Therefore, when the device is submerged in water, the fringe width will diminish.

Average velocity is defined as the difference between the change in position or displacement (x) and the time intervals (t) during which the displacement occurs. The average velocity may be positive or negative depending on the displacement's direction. The unit of measure for average velocity in the SI is meters per second (m/s or m[tex]s^{-1}[/tex]).

v = u + ats = ut + ½at²v² = u² + 2as

B = Klingon ship

Considering that the starship enterprise slows down steadily, the following would be the average velocity:

[tex]v_{a}__{i}[/tex] =( [tex]v_{a}__{i}[/tex] + [tex]v_{a}__{f}[/tex] )/2

where [tex]v_{a}__{f}[/tex] = 0 since it must come to a stop

[tex]v_{a}[/tex] = (50 + 0)/2

[tex]v_{a}[/tex] = 25 km/s

As a result, A must travel 100 km in addition to the distance B travels during that period before coming to a stop:

[tex]d_{A}[/tex] = [tex]d_{B}[/tex] + 100

25t = 20t + 100

5t = 100

So,

[tex]d_{A}[/tex] = 25t

[tex]d_{A}[/tex] = 25(20)

[tex]d_{A}[/tex] = 500 km

and

[tex]d_{A}[/tex] = [tex]v_{a}__{i}[/tex] × t + [tex]\frac{1}{2} a t^2[/tex]

500 = 50(20) + [tex]\frac{1}{2} a(20)^2[/tex]

Answers

The correct answer for percentage of the compound is left after 3.32 minutes is 55 % .

We use the formula A(t) = A0e-kt for decomposition, where A0 is the initial amount of decomposed substance at t = 0, k is the decay constant, t is the time elapsed, and A(t) is the amount after time t.

The percentage of decomposed compound left after a time t is, [A(t)], divided the the initial amount, [A0], time 100, or A/A0*100:

A = A0e-kt

A/A0 = e^- 0.00586t, [k = 0.00299, divide both sides by A0]

A/Ao = e^(-0.00299*199), [t = 3.32 min*(60 sec/ 1 min) =199 sec]

A/A0 = . 0.551= 55%, (* 100, rounded)

The Arrhenius equation is k = Ae(-Ea/kT), where A is the frequency or pre-exponential factor and e(-Ea/RT) is the fraction of collisions at temperature T that have enough energy to overcome the activation barrier (i.e., have energy greater than or equal to the activation energy Ea).

In the reaction, 3 moles of compound e are consumed to give 2 moles of compound g.

For 1 mole of compound e consumed to form =

[tex] \frac{2}{3} \: moles \: of \: g \: formed.[/tex]

The compound e is decreasing at the of = 0.69 mol/s

So, the rate at which g is increasing is,

[tex] = \frac{2}{3} \times 0.69[/tex]

[tex]= 0.46 \: mol/ s[/tex]

Therefore, compound f is increasing at the rate of 0.46 mol per second.

An inert atmosphere was obtained by adding nitrogen in a room that measures and has a 8.00 ft ceiling. how many liters of nitrogen were used to fill the room?

Answers

An inert atmosphere was obtained by adding nitrogen in a room that measures 11.0 ft x 11.0 ft and has a 8.00 ft ceiling. The number of liters of nitrogen that were used to fill the room is : (D) 2.74 x 104  Liters.

The number of liters of nitrogen that were used to fill the room

= Volume of room in cm3 x 1 Liters / 103 cm3

Volume of room in cm3 = 11.0 ft x  (30.48 cm / 1 ft) x  11.0 ft x  (30.48 cm / 1 ft) x 8.00 ft x (30.48 cm / 1 ft)

= 27410707.501 cm3  or 2.741 x 107 cm3

And since  1 Litres = 103 cm3

Volume of room in cm3  = 2.74 x 107 cm3

Now putting these values in the above equation we get

So, the number of liters of nitrogen that were used to fill the room

= Volume of room in cm3 x 1 Liters / 103 cm3

= 2.74 x 107 cm3  x 1 Liters / 103 cm3

= 2.741 x 104  Liters

Thus, an inert atmosphere was obtained by adding nitrogen in a room that measures 11.0 ft x 11.0 ft and has a 8.00 ft ceiling. The number of liters of nitrogen that were used to fill the room is 2.74 x 104  Liters.
