## Homework Statement

I need help with this question: http://img804.imageshack.us/img804/2278/unledsbg.jpg [Broken]

For a, I got omega = 18.63 rad/s by using methods of conservation of energy. Can someone tell me if I did this right? If not, please help me out! To be honest, I thought I had to use conservation of momentum for this since it involves a collision, but its equations dont involve angular velocity.

## Homework Equations

Conservation of energy/momentum

## The Attempt at a Solution

a) omega = 18.63 rad/sec
