## Homework Statement

There is a 2-D block with height

**H**, width

**W**, and mass

**M**. (H > W)

A force

**F**is applied from behind the block at a height

**0.1H**from the ground. If the coefficient of friction is

**μ**, what does the force F need to be to cause the block to tip backwards?

## Homework Equations

F x r

## The Attempt at a Solution

I know that if the we are interested in tipping the block forwards, then we set

**F**x

**r**= m

**g**x

**r**and solve for F. Since the question asks for when it tips backward, how do you find the solution?
