Homework Statement
Assume the ramp and block make the following coefficients of friction: (μs=0.9 μk=0.3)
and the 2 kg mass is placed at rest on the ramp and a horizontal force F is also applied.

What is the biggest magnitude force F that can be applied and the mass remains stationary?
Homework Equations
I know that FN = 20cos40 = 15.32N
F|| = 20sin40= 12.85N
However will I need to subtract any components from Fn and so on?
The Attempt at a Solution
No idea what to do, I did the problem without friction and for that F has to be 16.8N, but no idea what to do with friction incorporated into it.
