A small ball of mass m is aligned above a larger ball of mass M = 2.1 kg (with a slight separation, as with the baseball and basketball of Figure (a)), and the two are dropped simultaneously from height h = 2.1 m. (Assume the radius of each ball is negligible compared to h.) (a) If the larger ball rebounds elastically from the floor and then the small ball rebounds elastically from the larger ball, what value of m results...

Due in 37 minutes Average Force A golf ball of mass 42.1 g is dropped from a height h = 1.27 m onto a hard floor and bounces back to exactly that same height. What is the average force (in N) on the ball during the 0.01 1 s that it was in contact with the floor? (Please don't forget to convert the golf ball's mass to kg!) Incorrect.

1- A ball with mass M, moving horizontally at 2.8 m/s, collides elastically with a block with mass 3.6M that is initially hanging at rest from the ceiling on the end of a 58-cm wire. Find the maximum angle through which the block swings after it is hit, in degrees. 2- A 0.15 kg glider is moving to the right on a frictionless, horizontal air track with a speed of 0.72 m/s. It has a head-on collision with a 0.30...
