26-30. The ski slopes at Bluebird Mountain make use of tow ropes to transport snowboarders and skiers to the summit of the hill. One of the tow ropes is powered by a 22-kW motor which pulls skiers along an icy incline 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. A. Determine the cumulative weight of all these skiers. B. Determine the force required to pull this amount of weight up a 14° incline at a constant speed. C. Determine the speed at which the skiers will ascend the hill.

Instantaneous Power

Power is defined in physics as the amount of energy transmitted or transformed per unit time. The watt is the unit of electricity in the International System of Units, equivalent to one joule per second.

Question

26-30. The ski slopes at Bluebird Mountain make use of tow ropes to transport snowboarders and
skiers to the summit of the hill. One of the tow ropes is powered by a 22-kW motor which pulls

of 48 kg hold onto the rope and suppose that the motor operates at full power.
A. Determine the cumulative weight of all these skiers.
B. Determine the force required to pull this amount of weight up a 14° incline at a constant speed.
C. Determine the speed at which the skiers will ascend the hill.
