A 53.6 kg circus performer bobs up and down at the end of a long elastic rope at a rate of once every 2.80 s. The elastic rope obeys Hooke's law. Find how much the rope is extended beyond its unloaded length when the performer hangs at rest.

** I think Im missing a step when i do this problem. Help would be greatly appreciated**
