Ah true okay thank you sir, help very much appreciated, so then I would just do:
gsinθ - ugcosθ = a
Now does the equation above work? because I think I remember trying this cancelling out all of the m's, and I got a wrong answer, but I probably did my math wrong. I'll check once I finish with...
F=ma
Fg - Ff = ma
mgsin(theta) - umgcos(theta) = ma
I have two masses to remove, not just one :/ So i can't just simply simplify to:
gsin(theta) - ugcos(theta) = a right?

Homework Statement
So basically this is a two part question, first part was find acceleration of the system (which i already found) with a coefficient of friction of 0.1. B) asks you what coefficient you need for the object not to move?
