Suppose that the ball in the last question is dropped from the same height as before, but this time it is attached to a light parachute. Compare the kinetic energy just before the ball hits the floor to your previous answer.
1. The kinetic energy just before the ball hits the floor is (the same/larger/smaller) .
2. In this case, mechanical energy (is/is not) conserved.
