A 74.0kg person is put on an exercise program by a physical therapist, the goal being to burn up 550 food calories in each daily session. Recall that human muscles are about 21.0% in converting the energy they use up into mechanical energy. The exercise program consists of a set of consecutive high jumps, each one 40.0cm into the air (which is pretty good for a human) and lasting 1.50s , on the average.
