which of these is the best example of an elastic collision?
a rubber ball is dropped from 1.2 m and bounces back up to a height of 0.8 m.

a billiard ball strikes another of the same mass at rest and stops, and the second ball then moves with the same velocity as the first ball.

a cart rams a similar cart and latches onto it with a loud clack.

a cart rams another with a compressed spring, which is released, pushing them apart.
two objects, a and b, each of mass 0.22 kg, are moving at 0.52 m/s directly toward each other. a completely inelastic collision occurs and both objects stop. what percentage of the total kinetic energy is changed into other forms of energy?
