A 300-g ball is dropped at rest from a height 3.0 m above the horizontal floor. The ball bounces off the floor with an initial speed of 2.0 m/s. If the ball is in contact with the floor for 150 ms, what is the magnitude of the average force on the ball associated with the impact

A 4.00 −kg ball is dropped from a height of 14.0 m above one end of a uniform bar that pivots at its center. The bar has mass 5.50 kg and is 7.40 m in length. At the other end of the bar sits another 5.30 −kg ball, unattached to the bar. The dropped ball sticks to the bar after the collision. How high will the other ball go after the collision?

A ball is held at rest at some height above a hard, horizontal surface. Once the ball is released it falls, hits the surface, and starts bouncing vertically up and down. Suppose that with each bounce the ball loses a fixed fraction p (with 1>p>0) of its energy. This loss could be due to a number of reasons (inelasticity, drag, etc) that are left unspecified. How many times will the ball bounce before coming to rest (if at all)? Provide...

A ball, dropped onto a hard floor from a height of 2 meters, bounces to a height of 1.8 meters, 90% of the initial height. Each subsequent bounce is 90% the height of the previous one. Find the total distance the ball travels up and down (i.e. after the first collision with the ground it has traveled 2 meters down and 1.8 meters up, giving a total distance of 3.8 meters).
