1. The problem statement, all variables and given/known data A skier of mass 70 kg is pulled up a slope by a motor-drive cable. a. How much work is required to pull him 60 m up a 30° slope (assumed frictionless) at a constant speed of 2 m/s? b. What power must a motor have to perform this task? Help would be greatly appreciated! 2. Relevant equations 3. The attempt at a solution I will be attaching pictures in a reply to this in a minute, and these pictures will have my work. I have no idea if I did it correctly, as my textbook does not have an answer for this proble, but I don't feel totally clueless, so that's good? The thing is, theres no acceleration, so it's kind of confusing, because the normal W= Fd doesn't seem to work because I keep getting 0 N, because a=0, but when I solve using ΔU, I actually get something, but once again, I have no clue if it is correct. Any help is greatly appreciated!!
