After getting a drink of water, a hamster jumps onto an exercise wheel for a run. A few seconds later the hamster is running in place with a speed of 0.8 m/s. Find the work done by the hamster to get the exercise wheel moving, assuming it is a hoop of radius 0.10 m and mass 5.9 g.(adsbygoogle = window.adsbygoogle || []).push({});

I'm not sure how to solve this one. I think you use

Work=(torque) x (delta theta)

Torque = rF

but, after that, i'm not sure what theta would be. Am I even using the right set of equations? Thanks for all the help!
