Show menu

A giant swing is an artistic gymnastics element in which a gymnast rotates around an axis while in a fully extented position.

1) What is the minimum angular speed of the gymnast to make such a swing?

2) Find the force required by the arms to keep spinning.

3) Suppose that a gymnast makes one spin per second. Calculate his angular speed and the force on the arms at the bottom and the top positions.

State any assumptions that you make.
