1. The problem statement, all variables and given/known data
A block of mass m slides down a frictionless track, then around the inside of a circular loop-the-loop of radius R. From what minimum height h must the block start to make it around the loop without falling off? Give your answer as a multiple of R. (h/R=?)
2. Relevant equations
KE= 1/2mv^2
Ug= mgh
3. The attempt at a solution
I need help getting started! Can someone talk me through this one?
