Question Details:

A 2-lb sphere A is moving to the left with a velocity of 40 ft/s when it strikes the inclined surface of a 5-lb block B which is at rest. The block is supported by rollers and is attached to a spring of constant k=12 lb/in. Knowing that the coefficient of restitution between the sphere and the block is e=.7, and neglecting friction, determine the maximum deflection of the spring.
