Answer 1

Answer:

9.8 m/s²

Explanation:

Since the ball rises for 2.5 s, the time to fall is 2.5 s. The acceleration is 9.8 m/s2 everywhere, even when the velocity is zero at the top of the path. Although the velocity is zero at the top, it is changing at the rate of 9.8 m/s² downward.

Answers

Answer: hope you find the explanation useful!

Explanation:

Consumer behavior considers numerous reasons why individual, situational, mental, and social individuals look for items, purchase, use, and afterward discard them.

Evaluative criteria are positive qualities that are imperative to you, for example, the cost of the knapsack, the size, the number of compartments, and shading. A portion of these attributes are valued highly as compared to others. For instance, the size of the rucksack and the cost may be more imperative to you than the shading except if, state, the shading is hot pink, and you despise pink.

The drawing shows a person looking at a building on top of which an antenna is mounted. The horizontal distance between the person’s eyes and the building is 85.5 m. In part a the person is looking at the base of the antenna, and his line of sight makes an angle of 38.9o with the horizontal. In part b the person is looking at the top of the antenna, and his line of sight makes an angle of 41.6o with the horizontal. How tall is the antenna?

Answers

height of building (h1):
tan(38.9°) = opposite / adjacent
tan(38.9°) = h1 / 85.5
85.5 tan(38.9°) = 68.990 (5sf)

height of building with antenna (h2):
tan(41.6°) = opposite / adjacent
tan(41.6°) = h2 / 85.5
85.5 tan(41.6°) = 75.910 (5sf)

height of antenna (h2 - h1)
75.910 - 68.990 = 6.92m

F = 1 N

Explanation:

F = Gm₁m₂/r² + kq₁q₂/r²

F = (Gm₁m₂ + kq₁q₂) / r²

F = [6.674(10⁻¹¹)(0.50)(0.25) + 8.988(10⁹(5(10⁻⁶))(-2(10⁻⁶))] / 0.30²

F = 0.9986666667593611111...

F = 1 N

notice that the electrostatic force by itself results in an attraction of

0.99866666666666666666... N

The gravitational force is quite negligible in this example.

A bucket crane consists of a uniform boom of mass
M = 201 kg and length L= 59.05 ft that pivots at a point on
the bed of a fixed truck. The truck supports an elevated bucket
with a worker inside at the other end of the boom, as shown in
the figure. The bucket and the worker together can be modeled
as a point mass of weight 201 lb located at the end point of
the boom.
Suppose that when the boom makes an angle of 68.7° with the
horizontal truck bed, the bucket crane suddenly loses power,
causing the bucket and boom to rotate freely toward the
ground. Find the magnitude of the angular acceleration la of
the system just after the crane loses power. Take the rotation
axis to be at the point where the boom pivots on the truck bed.
Use g = 9.81 m/s2 for the acceleration due to gravity. For unit
conversions, assume that 1 m = 3.28 ft and 1 lb = 4.45 N.
Express your answer to at least two decimal places.

Answers

Newton's second law for rotational motion allows finding the results for the angular acceleration of the system at the moment of losing power is:

              α =0.616 rad / s²

Newton's second law for rotational motion relates the torque to the moment of inertia and the angular acceleration, in the special case where the angular acceleration is zero, it is called the rotational equilibrium condition.

           [tex]\sum \tau = I \alpha[/tex]

           [tex]\tau = F \ r \ sin \theta[/tex]

where τ is the torque, F is the force, r the distance to the pivot point and θ the angle between the force, the distance, I is the moment of inertia and α is the angular acceleration.

In this case they indicate the values ​​in several different units, let's reduce to the international system of measurements (SI).

Beam mass M = 201 kg Beam length L= 59.05 ft (1m / 3.28 ft) = 18.0 m Worker and basket weight Wh = 201 lb (1N / 0.2248 lb) = 894.1 N Beam angle tea = 68.7º

We place our reference system at the base of the beam on the truck and counterclockwise turns as positive, and in the attached we see a free-body diagram of the system.

   

          [tex]W_m \ L \ sin 68.7 + Mg \ \frac{L}{2} \ sin 68.7 = I \alpha[/tex]

The moment of inertia is an additive scalar quantity, the total moment of inertia is the moment of inertia of the pen plus the moment of inertia of the man.

Moment of inertia of the beam with respect to one end.

           [tex]I_[/tex] = ⅓ ML²

moment of inertia of man

           [tex]I_m = M_m L^2[/tex]

Let's substitute

           [tex](W_m + \frac{Mg}{2} ) \ L \ sin 68.7 = (\frac{1}{3} M + m_m ) L^2 \alpha \\\alpha = \frac{(W_m + \frac{Mg}{2} ) sin 68.7 }{ (\frac{1}{3} M + m_m ) L }[/tex]

Let's calculate        

The mass of man is

           m = [tex]\frac{W_m}{g}[/tex]

           m = 894.1 / 9.8

           m = 91.2 kg

          [tex]\alpha = \frac{(894.1 +2.1 \ 9.8 ) \ sin 68.7 }{ 18.0 ( \frac{201}{3} + 91 }[/tex]

          α = 0.616 rad / s²

In conclusion using Newton's second law for rotational motion we can find the results for the angular acceleration of the system at the moment of losing power is 0.616 rad / s²

A plane moves 599 m northeast along a runway.
If the northern component of this displacement
is 89 m, how large is the eastern component?

Answers

The eastern component of the plane's displacement is 592.35 m.

The given parameters;

the resultant of the plane displacement = 599 mthe northern component of this displacement, Y = 89 mLet the eastern component of this displacement = X

The eastern component of the plane's displacement is calculated by applying Pythagoras theorem as follows;

X²  + Y² = 599²

X² + 89² = 599²

X² = 599²  - 89²

X² = 350880

X = √350880

X = 592.35 m

Thus, the eastern component of the plane's displacement is 592.35 m

If a pool and a cup of water had the same temperature, which would have greater thermal energy?Why?

Answers

Despite being the same temperature, the swimming pool is a much larger thermal energy store than the beaker of water.

What is thermal energy?

Thermal energy is the energy contained within a system that controls its temperature. The flow of thermal energy is defined as heat.

Thermodynamics is a branch of physics that deals with how heat is transferred between different systems and how work is done in the process.

Thermal energy sources include natural gas, coal, and oil, as well as solar, heat pump electric, and geothermal heat.

A swimming pool and a beaker of water can both be the same temperature.

Despite being the same temperature, the swimming pool contains significantly more thermal energy than the beaker of water. A heated swimming pool's thermal store contains a lot of energy.

Thus, If a pool and a cup of water had the same temperature, then swimming pool has a much larger thermal energy.

Answers

The vertical component of the velocity after the given time is -9.8 m/s while the horizontal component of the velocity is 16 m/s.

The given parameters;

initial horizontal velocity, vₓ = 16 m/sinitial vertical velocity, [tex]v_y =0[/tex]time interval 1 seconds

The components of the velocity can be horizontal or vertical velocity.

The vertical component of the velocity is affected by acceleration due to gravity while the horizontal component of the velocity is not affected by gravity.

The vertical component of the velocity is calculated as;

[tex]v_y = v_0_y -gt\\\\v_y = 0 - (1\times 9.8)\\\\v_y = -9.8 \ m/s[/tex]

The horizontal component of the velocity is constant since it is not affected by gravity.

The horizontal component of the velocity = 16 m/s

Thus, the vertical component of the velocity after the given time is -9.8 m/s while the horizontal component of the velocity is 16 m/s.
