Kinetic Energy and Collision Question

[QUOTE="haruspex, post: 5501126, member: 334404"] Momentum must be conserved. Their common mass centre therefore continues at the same velocity. Maximum KE loss occurs when they coalesce. If it is a glancing blow, and the masses are not sticky, then their velocities parallel to the plane of contact will not change. Maximum KE loss when will be when their velocity components along the line of contact become the same. If they are irregular shapes and the blow is glancing, it gets complicated since some of the energy may turn into rotational energy, so it depends whether you count that as conserved or lost.
