a 4.5 kg sled is pulled across a level snow with a force of 225N on a rope that is 35° above the horizontal. If the sled moves 65.3m in 2.5minutes, how much work does the person do on the sled? How much power is exerted on the sled? The person is pulling as hard as possible on the rope, how else can the amount of work be increased?
A skier is pulled by a towrope up a frictionless ski slope that makes an angle of 12 with the horizontal. The rope moves parallel to the slope with a constant speed of 1.0 m/s. The force of the rope does 900 J of work on the skier as the skier moves a distance of 8.0 m up the incline. (a) If the rope moved with a constant speed of 2.0 m/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) 1.0 m/s and (c) 2.0 m/s?
