Two blocks of masses m, = 4.00 kg and m, = 8.00 kg are each released from rest at a height of 5.00 m on a frictionless track, as shown in the figure, and undergo an elastic head-on collision. Find the maximum height to which block m, rises after the collision. т т2 5.00 m 5.00 m

A 71.1-kg basketball player jumps vertically and leaves the floor with a velocity of 1.91 m/s upward. (a) What impulse does the player experience? magnitude      N · s direction      ---Select--- upward downward forward backward The magnitude is zero. (b) What force does the floor exert on the player before the jump? magnitude      N direction      ---Select--- upward downward forward backward The magnitude is zero. (c) What is the total average force exerted by the floor on the player if the player is in contact with the floor for 0.450 s during the jump? magnitude      N direction      ---Select--- upward downward forward backward The magnitude is zero.

A 0.400 kg hammer is moving horizontally at 5.00 m/s when it strikes a nail and comes to rest after driving it 1.00 cm into a board. (a) Calculate the duration of the impact. (b) What was the average force exerted on the nail?
