Askier is pulled by a tow rope up a frictionless ski slope that makes an angle of 7.1° with the horizontal. the rope moves parallel to the slope with a constant speed of 0.60 m/s. the force of the rope does 600 j of work on the skier as the skier moves a distance of 4.6 m up the incline. (a) if the rope moved with a constant speed of 2.8 m/s, how much work would the force of the rope do on the skier as the skier moved a distance of 4.6 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) 0.60 m/s and (c) 2.8 m/s?
