## Homework Statement

see attached diagram, one mass is given at 10 kg while the other is unknown. The friction is given an (mu)=0.25 for both masses

## Homework Equations

i need to find Magnitude of M for when the 10KG Mass slides down the plane and again for when the 10KG mass slides up the plane

## The Attempt at a Solution

on the 10kg mass

mgsin(thetha)=49.05

mgcos(thetha)=84.96

I don't know where to go from here, I am really stuck with this can anyone help please?

On the Unknown Mass

mgsin(thetha)=8.5m

mgcos(thetha)=4.905m
