The 3.7-lb rod ABAB is hanging in the vertical position. A 1.5-lb block, sliding on a smooth horizontal surface with a velocity of 12 ft/s, strikes the rod at its end BB.
Determine the velocity of the block immediately after the collision. The coefficient of restitution between the block and the rod at BB is e = 0.80.

A 1-lb all is attached to a 30” long cord as shown. The
horizontal cord and ball are released from rest. When the cord
reaches a vertical position, the ball strikes a 5-lb steel block
initially at rest on a frictionless surface. If the coefficient of
restitution between the ball and the block is 0.9, what is the
speed of the ball before and after impact? What is the speed of the
block just after impact?

The spring bumper is used to arrest the motion of the 9 lb
block, which is sliding toward it at 5 ft/s . As shown, the spring
is confined by the plate P and wall using cables so that its length
is 1.5 ft.

required unstretched length of the spring so that the plate is not
displaced more than 0.2 ft after the block collides into it....
