Two blocks, each of mass m = 6.90 kg , are connected by a massless rope and start sliding down a slope of incline θ = 40.0 ∘ at t=0.000 s. The slope's top portion is a rough surface whose coefficient of kinetic friction is μk = 0.350. At a distance d = 2.90 m from block A's initial position the slope becomes frictionless. What is the velocity of the blocks 4.10 s after the blocks have started moving? Assume...
