A skier is pulled by a tow rope up a frictionless ski slope that makes an angle of 11° with the horizontal. The rope moves parallel to the slope with a constant speed of 0.97 m/s. The force of the rope does 730 J of work on the skier as the skier moves a distance of 7.3 m up the incline. (a) If the rope moved with a constant speed of 2.7 m/s, how much work would the force of the rope do on the skier as the skier moved a distance of 7.3 m up the incline? At what rate is the force of the rope doing work on the skier when the rope moves with a speed of (b) 0.97 m/s and (c) 2.7 m/s?
