A 0.343 kg croquet ball makes an elastic head-on collision with a second ball initially at rest. The second ball moves off with one half the original speed of the first ball. 1) What is the mass of the second ball? And 2) what fraction of the original kinetic energy gets transferred to the second ball?
This solution determines the mass of the second ball and what fraction of kinetic energy is transferred using the conservation of momentum principle. An annotated diagram is provided as well as step-by-step calculations and brief explanations.
