## Homework Statement

No specific question.

How would one find the critical angle of a ramp given the mass of the block sliding down it and the mu between ramp and block?

It's not a single question but something my teacher explained that i didn't understand.

## Homework Equations

F=(mu)mg

F=ma

I'm not sure of any more

## The Attempt at a Solution

I just don't get how to calculate the critical angle.

Is there a formula or a way to derive some equations?

What i know is i have to get the gravity vector that points down the ramp to exceed friction.

But how would i set up that equation?
