Assignment:
A skier is pulled by a tow rope up a frictionless ski slope that makes an angel of 12 degree with the horizontal. The rope moves parallel to the slope with a constant speed of 1.0m/s. The force of the rope does 900J of work on the skier as the skier moves a distance of 8.0m up the incline. (a) If the rope moved with a constant speed of 2.0m/s, how much work would the force of the rope do on the skier as the skier moved a distance of 8.0 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)1.0m/s? and (c) 2.0m/s?
Provide complete and step by step solution for the question, use formulaes.
