Question

A gymnast on a suspended platform holds on to a 5 m long rope and swings by gravity alone (i.e., without pushing off) to another platform directly below the rope’s suspension point. Approximate how long it takes to swing from point A to point B.

Answer 1

she will never reach either point

Answer 2

The period of a simple pendulum is 2π√(L/g) where L is the length of the pendulum and g is gravity. In this case

t = 2π√(L/g) = 4.487 seconds. However he only swings half of that, so the time is 2.244 seconds.
