A winch, located at M, pulls a box up an incline with a cable. The distance from the box to the winch is s. Suppose that, starting from rest, the box travels the full distances and the tension in the cable is a constant value T. Assume the box has mass m and a sliding coefficient of friction of Mk. What is the speed of the box, UM, when it reaches the winch at point M? Assume the values 8 = 9.81 m/s², T =300 N, k = 0.3, m = 20 kg, 0 = 30 deg, and s=10 m.
