9. (II) A measure of inelasticity in a head-on collision of two objects is the coefficient of restitution, e, defined as VA – v e = VB VA - where v'a - vB is the relative velocity of the two objects after the collision and vB - VA is their relative velocity before it. (a) Show that e = 1 for a perfectly elastic collision, and e = 0 for a completely inelastic collision. (b) A simple method for measuring the coefficient of restitution for an object colliding with a very hard surface like steel is to drop the object onto a heavy steel plate, as shown in Fig. 9-41. Determine a formula for e in %3| %3D terms of the original height h and the maximum height h' reached after collision. h' IURE 9-41 Problem 49. VA IVA asurement of coefficient estitution.

A small ball of mass m is placed on top of a large ball of mass 3m. Both balls are dropped simultaneously from a height h = 3.75 m as shown in the figure. Assuming the radius of the large ball and small are small and thus negligible in comparison to the height they are being dropped meaning the small ball has the same speed the large ball has when it hits the ground. If the large ball rebounds elastically from the floor, collides with the small ball, stops and then the small ball rebounds elastically from the large ball, find the maximum height the small reaches.
