Problem 94P

Energy Sharing in Elastic Collisions. A stationary object with mass mB is struck head-on by an object with mass mA that is moving initially at speed v0. (a) If the collision is elastic, what percentage of the original energy does each object have after the collision? (b) What does your answer in part (a) give for the special cases (i) mA = mB and (ii) mA = 5mB? (c) For what values, if any, of the mass ratio mA/mB is the original kinetic energy shared equally by the two objects after the collision?
