Problem: A young lady is jumping rope; she always jumps so that both feet leave the ground at the same instant of time. Each of her jumps reaches a height of 14.5 cm off of the ground. (This means that she moves upward by 14.5 cm after her feet leave the ground.) The weight of the young lady is 429 N.
Part I: What is her speed each time she leaves the ground?
(Answer: v=..........m/s)
I need help to find her speed each time she leaves the ground.
