Centripetal force relation to angular momentum

[turnip]

Homework Statement

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.

Homework Equations

Fc= mv^2/r

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?
