Two blocks are connected by a massless, unstretchable rope which goes over a frictionless pulley. Block 1, mass m1, slides up the plane where there is friction between the plane and block. The coefficient of friction between the plane and block is a function of the block's position on the plane. It is given by u=u₀ (1+x²/S²) where u₀ and S are known constants. How fast will block 1 be moving when block 2, mass m2, has moved down a distance H if it started from rest? (All masses and θ are known. )
