The ski slopes at one of the parks in Killington, VT make use of tow ropes to transport skiers to the summit of the hill. One of the tow ropes is powered by a 11-kW motor which pulls skiers along an icy incline (negligible friction) of 14° at a constant speed. Suppose that 18 skiers with an average mass of 48 kg hold onto the rope and suppose that the motor operates at full power. (Hint: A 11 kilowatt motor at full power does 11000 J of work per second.) Determine the force required to pull this amount of weight up the incline at a constant speed. a) 8215 N b) 2048 N                                 c) 8467 N
