A person reaches a maximum height of 55cm when jumping straight up from a crouched position.During the jump, the person's body from the knees up uses a distance of around 45cm.(Assume the entire body rises this much during jump).

A) What is the initial speed with which the Pearson leaves the ground to reach a height of 55cm?

B) In terms of the jumper's weight, what force does the ground exert on him or her?
