1. The problem statement, all variables and given/known data
how could one prove a relation between centripetal force and angular velocity?

i have tried to find this in a search but nothing came up.

2. Relevant equations
Fc= mv^2/r

3. The attempt at a solution
i guess this involves some sort of substitution for velocity and angular momentum. the problem is, which equation could/should i use?
