Hey, I have been fiddling with with problem all day today and I really have no idea how to even approach it. I was wondering if anyone could help shed some light onto it for me. Any help would be greatly appreciated!(adsbygoogle = window.adsbygoogle || []).push({});

[HRW7 7.P.042.] A skier pulled by a tow rope up a frictionless ski slope that makes an angle of 12° with the horizontal. The rope moves parrallel to the slope with a constant speed of 1.0 m/s. The force of the rope does 950 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?

___________J

(b) At what rate is the force of the rope doing work on the skier when the rope moves with a speed of 1.0 m/s?

__________W

(c) At what rate is the force of the rope doing work on the skier when the rope moves with a speed of 2.0 m/s?

________W

Thanks so much!
