Homework Equations
F_spring = kx, where x is the distance compressed
f_friction = uN
The Attempt at a Solution
Forces acting on m: N_1 up, mg down, f_friction to right
Forces acting on M: N_2 up, Mg+N_1 down, f_spring to the right
Block m will still be in equilibrium as long as the force exerted by the spring equals the force of friction:
kx = uN_1
The block isn't accelerating in y-direction so N_1 = mg
So kx = u*mg
x = u*mg/k
Does that look fine?
