the speed of an object increases by 30 m/s in 10 seconds. what is its acceleration?

Answer:

3.13m/s²

Explanation:

90×1000/3600 note: 1h- 3600s

=25m/s

a=v/t

a= 25m/s ÷ 8s

a= 3.125 / 3.13m/s²

Answer:

H = Vo t + 1/2 g t^2

Velocity and gravitational acceleration are vector quantities - it is very important to use the correct signs for these quantities to get the correct quantity for H the distance traveled.

Answer:

Below

Explanation:

To find the acceleration of the car you can use this formula :

     vf = vi + at OR a = v/t

I'm going to use the first one because it explains the steps more clearly :

vf = 24 m/s

vi = 0 m/s

t = 9.4 s

a = ?

     24m/s = 0 + (a)(9.4s)

     24m/s = a9.4

Divide both sides by 9.4

     a = 2.55319 m/s^2

Round to 3 sig figs

     a = 2.6 m/s^2

Hope this helps! Best of luck <3

Answer:

Distance= 300 km

Displacement= 130

Explanation:

When you find distance you have to add

When you find displacemnet you subtract

If a car drives 215 kilometers west and then 85 kilometers south, then the distance and displacement of the car would be 300 kilometers and kilometers respectively.

Displacement is a vector quantity. This indicates that it has both a direction and a magnitude and that it is visually represented as an arrow that points from the starting position to the ending position.

As given in the problem, if a car drives 215 kilometers west and then 85 kilometers south, then we have to find the distance and displacement of the car,

The distance traveled by car = 215 kilometers + 85 kilometers

                                                = 300 kilometers

The displacement covered by the car = √(215² + 85²)

                                                               = 231.2 Kilometers

Thus, the distance traveled by car would be 300 Kilometers and the displacement would be 231.2 Kilometers in the southwest direction.

Newton's second law allows finding the answer for the force that attracts the body is 127.4N

Newton's second law indicates that the force that is the interaction between two bodies is directly proportional to the product of the mass and the acceleration.

            F = m a

Where the bold letters indicate vectors, F is the force, m the mass, and the acceleration of the body.

When a body is close to the Earth there is an interaction between the body and the planet, we call this interaction weight, it is given by the relationship

           W = m g

Where W is the force called weight, m ​​the mass of the body and g the acceleration of the body, which in this case is called the gravity acceleration   (g = 9.8 m / s²)

They indicate that the mass of the body is m = 13 kg, let's calculate the weight

           W = 13  9.8

           W = 127.4 N

In conclusion using Newton's second law we can find the answer for the force that attracts the body is 127.4N

Explanation:

The initial velocity of the marble from the given position is  1.49 m/s.

The given parameters;

The time of motion of the marble from the given height is calculated as;

[tex]h = v_yt + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\t = \sqrt{\frac{2h}{g} } \\\\t = \sqrt{\frac{2\times 0.8}{9.8} }\\\\t = 0.404 \ s[/tex]

The initial horizontal velocity of the marble is calculated as follows;

[tex]X = v_0_xt\\\\v_0_x = \frac{X}{t} \\\\v_0_x = \frac{0.6}{0.404} \\\\v_0_x = 1.49 \ m/s[/tex]

Thus, the initial velocity of the marble from the given position is  1.49 m/s.

Answer:

Electric Field intensity is zero.

The reason for that is:

All charges are placed at equal distances from the center of the square and have same magnitude and sign. This means they will exert equal and opposite forces on the test charge at the center. Net force will become Zero.

The second ball traveled a greater distance when compared to the first ball because the second ball spent more time in motion.

The given parameters;

The distance traveled by each ball is calculated using the second equation of motion as shown below.

The distance traveled by the first ball is calculated as follows;

[tex]h = u_0t + \frac{1}{2} gt^2\\\\h = 0 + \frac{1}{2} gt^2\\\\h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 1^2)\\\\h = 4.9 \ m[/tex]

The distance traveled by the second ball is calculated as follows;

[tex]h = \frac{1}{2} gt^2\\\\h = (0.5\times 9.8\times 3^2)\\\\h = 44.1\ m[/tex]

Thus, the second ball traveled a greater distance because it spent more time in motion.
