1. A ring 1.5 m in diameter is pivoted at one point on its circumference so that it is free to rotate about a horizontal axis. Initially, the line joining the support and center is horizontal.

a. If released from rest, what is its maximum angular velocity.

b. What must its initial angular velocity b if it is to jst make a complete revolution ?

2. Relevant equations

V=rw

3. The attempt at a solution

I don't know how to treat the ring as. Should I treat it as a hoop ?

How should I calculate maximum velocity ? I don't know what formula to use.
