A 74 g ball B dropped from a height ho=1.9 m reaches a height h₂= 0.25 m after bouncing twice from identical 250 plates. Plate A rests directly on hard ground, while plate Crests on a foam-rubber mat. B L ho hy The Determine the coefficient of restitution between the ball and the plates. The coefficient of restitution between the ball and the plates is

Two discs of same size and mass are B colliding on a frictionless Air-Hockey table. Disc A is sliding towards disk B (at rest) on their tangent as shown. Determine the velocity of disc B after the impact and the energy lost in the collision, if the A coefficient of restitution is e. Solve the problem algebraically first, then solve it for v = 1m/s and e=0.85

A 42-lb suitcase slides from the rest 20 ft down the ramp. The suitcase has an initial velocity down the ramp of v_A = 7 ft/sft/s and the coefficient of kinetic friction along AB is μk = 0.19. (Figure 1) (a)  How long does it take to go from A to C? Express your answer to three significant figures and include the appropriate units. The answer is not 1.561 seconds.

A ball is dropped from rest from the roof of a small building. If the building is 10 m high determine: (a) the ball's velocity at impact; and (b) How long the ball takes to hit the ground?

Determine the coefficient of restitution e for a steel ball dropped from rest at a height h above a heavy horizontal steel plate if the height of the second rebound is h2. Can someone please explain to me how the book is getting that equation?

Two spheres of different masses and initial velocities collide with each other on frictionless surface, as shown in Figure 5. Assume the collision is direct central and the coefficient of restitution e = 0.8, determine their velocities after the collision.
