in a time, t. 0 A ball of soft clay (mass, m) hits the floor with speed v and stops. Use momentum considerations to find the average force of the ball on the floor.
A ball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. If the ball hits the floor with a speed of 3.30 m/s and rebounds with a speed of 1.50 m/s, determine the following. (a) magnitude of the change in the ball's momentum in kg · m/s (Let up be in the positive direction.) (b) change in the magnitude of the ball's momentum in kg · m/s (Let negative values indicate a decrease...
A ball with a mass of 275 g is dropped from rest, hits the floor and rebounds upward. If the ball hits the floor with a speed of 2.30 m/s and rebounds with a speed of 2.00 m/s, determine the following. (a)magnitude of the change in the ball's momentum in kg · m/s (Let up be in the positive direction.) kg · m/s (b)change in the magnitude of the ball's momentum in kg · m/s (Let negative values indicate a...
A ball of soft clay with mass 1 kg falls from a height of 10 m starting at rest. When the clay hits the ground it flattens and comes to a stop. Which of the following is true? Gravity does work on the ball equal to 980 J, and all this energy is dissipated during the deformation of the ball on impact. Gravity does work on the ball equal to 98 J, and all of this energy is dissipated during...
G . A 6 0 - g ball of clay falls and an instant before it hits the ground it has a speed of 3.0 m/s. a. How much work did the floor do on t he clay to bring it to a stop? b. If the force that stopped the ball was 6 0 N, how long did it take for the ball to come to a stop?
A ball of mass m hits a eall perpendicularly and bounces off perpendicularly. The speed of the ball just before it hits the wall is vi and the speed just after striking the wall is also vi. What is the magnitude of the change in momentum of the ball? a. 0 b. mvi c. 2mvi d. 3mvi/2
A ball is dropped from 1.524 m and hits the floor with impact speed. Use conservation of energy to calculate the ball's speed when it hits the ground, the impact speed.
J, A falling 0.1 kg ball has a speed of 7.0 m/s just before it hits the floor and an upward speed of 5 0 ms immediately after it rebounds. The ball is in contact with the floor for 0.01 s. What is the magnitude (in N) of the average force exerted by the floor on the ball?
A dropped rubber ball of 1.5 kg mass hits the floor with a speed of 6m/s and rebound s to a height of 0.3m. What fraction of initial kinetic energy lost in the collision?
A bouncy, elastic ball of mass 1.20 kg moving with v = 5.70 m/s hits the wall at an angle of 30° and bounces off. If the collision lasted for 0.01 s, what is the average force exerted by the wall on the ball?
