Energy Sharing in Elastic Collisions. A stationary object
Chapter 10, Problem 94P(choose chapter or problem)
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 ?v?0. (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? = 5?mB?? (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?
