A 52.0 kg male dancer leaps 0.37 m high.
(a) With what momentum does he reach the ground?
(c) As the dancer lands, his knees bend, lengthening the stopping time to 0.050 s. Find the average force exerted on the dancer's body.
(d) Compare the stopping force with his weight.
(stopping force/dancer's weight)
what is the time first of all and then what do i do after that??
