a block of mass m is resting on a 20degree slope. The block has coefficients of friction mu_s =0.80 and mu_k =0.50 with the surface. It is connected via a massless string over a massless, frictionless pulley to a hanging block of mass 2.0 kg. (sorry didnt know of a way to distribute a picture)
what is the minimum mass m that will stick and not slip?
i drew 1 free body diagrams of the mass m and mass 2.
For the FBD of m1:
I have normal force, kinetic friction,static friction, the weight components of the mass, and the force of the second mass acting on the first one.
For the FBD of m2:
I have just the force acting on ms from m1, and the weight of m2.
im not quite sure if the block is accelerating kuz it says resting, but then again I am given coefficients of frictional forces. also can i equate the 2 tension forces of the ropes from the third law?
im pretty stumped, I am not sure how to proceed after drawing the FBD's.
