Question 4

A box of mass 75.8 kg is initially sliding upward (in the positive direction) on a rough incline that makes an angle α = 58o with the horizontal. As in the previous problem: a massless string is tied to the box, runs parallel to the incline, passes over a frictionless pulley and is tied to mass M = 85 kg hanging on the other end. Assume the coefficient of kinetic friction between the box and the surface of the incline is μk = 0.217. Find a, the acceleration of the masses. The direction is given by the sign of the answer: up the incline is positive, down the incline is negative.
