v=rw

## The Attempt at a Solution

I know that in order to solve this problem I need to find time, but I'm not sure how to do that. I know that I need time to be abel to find w and that r=0.60m I think. Any help would be great. Thank you. There is a picture that is attached to help with the problem.
