Question
A child bounces in a harness suspended from a door frame by three elastic bands.
(a) If each elastic band stretches 0.210 m while supporting a 7.35-kg child, what is the force constant for each elastic band?
(b) What is the time for one complete bounce of this child?
(c) What is the child's maximum velocity if the amplitude of her bounce is 0.210 m?
