5PRACTICE PROBLEM
As part of a physical exercise, a gymnast jumps straight up from a crouched position attaining a maximum height of approximately 60 cm. However, the gymnast's body above the knees rises approximately 52 cm above the ground. To simplify the calculations while yielding a realistic result, we shall make an assumption that the whole body rises 60 cm during the jump. What free-body diagram best represents the gymnast while he is pushing up from the ground?
