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...
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 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...
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
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 ball falls from height of 19.5 m, hits the floor, and rebounds vertically upward to height of 15.0 m. Assume that mall 0.390 kg. (a) What is the impulse (in kg. m/s) delivered to the ball by the floor? (b) If the ball is in contact with the floor for 0.0400 seconds, what is the average force (in N) the floor exerts on the ball?
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.
A 0.24 kg bouncy ball falls and bounces of the floor. The speed of the bouncy ball is 18 m/s before it hits the ground while the speed of the bouncy ball is 13.5 m/s on the rebound. It takes .02 seconds from the time the ball first touches the ground to the time when the ball first leaves the ground. What is the magnitude of the Average force on the ball?
