Question
When jumping straight up
from a crouched position, an average person can reach a maximum height
of about 60 cm. During the jump, the person’s body from the knees up
typically rises a distance of around 50 cm. To keep the calculations simple
and yet get a reasonable result, assume that the entire body rises this
much during the jump. In terms of this jumper’s weight w, what
force does the ground exert on him or her during the jump?
