a) Assuming that f=μN, show that the coefficient of (rolling) friction for the car moving down the inclined plane with a constant speed is gived by μ=m2/mccosθ. Use symbols, not numbers.
b)Prove that θ is equal to μk when the blcok sldies down the incline with a constant speed?(use symbols not numbers)
b2) if θ is the maximum angle of inlcline justbefore theblcok moves, what is μs in term of θ?
c)suppose that the blcok were made to move up the inclined plane with a uniform speed by suspending masses on a string over the pulley. Derive an equation for the coefficient of kinetic friction for this case in terms of the suspended masses, the mass of the block, and the angle of decline. (neglect friction and mass of pulley)

Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane
Two blocks with mass M1 and M2 are arranged as shown with M sitting on an inclined plane and connected with a massless unstretchable string running over a massless, frictionless pulley to M2, which is hanging over the ground. The two masses are released initially from rest. The inclined plane has coefficients of static and kinetic friction μs and μk respectively where the angle θ is small enough that mass M1 , would remain at rest due to static friction if...
