A 2.00 kg box is placed on a 20.0 m high point on a hill and released from rest. When the box reaches the bottom of the slope, its speed is 5.88 m/s. Determine the work done by friction (Enter your answer in units of J. Only enter the number using 3 significant figures. Be careful about the sign of the work.)
