A person reaches a maximum height of 62 cm when jumping straight up from a crouched position. During the jump itself, the person's body from the knees up 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.

Part A: With what initial speed does the person leave the ground to reach a height of 62 cm?

Part B: In terms of this jumper's weight W , what force does the ground exert on him or her during the jump?

I figured out the first part, but I can't figure out the second part. :(

Also,

It has to be a number? This is online homework and the answer is in the format:

F=W
