13)(pr) A van of mass 1055 kg sits at rest at a stop sign. A car of mass 715 kg travels with a speed of 2.25 m/s just before it rear-ends the van. Assume that the van is free to move following the collision (transmission is in neutral, no brakes being applied), and the collision is elastic. (See PSL 9.8.) a) Determine the final velocities (magnitudes and directions) of both vehicles. b) Verify that the total KE before the collision is equal to the total KE after the collision (as it should be for an elastic collision).
