1. The problem statement, all variables and given/known data A skier of mass 69.5 kg is pulled up a slope by a motor-driven cable. a) How much work is required to pull him a distance of 59.1 m up a 30.1° slope (assumed frictionless) at a constant speed of 2.07 m/s? 3. The attempt at a solution I started out this problem by finding out what that force of gravity parallel to the slope would be. mgsin(30.1)=341.57 N Then I figured I would find the total negative work that would be done for the whole slope so I multiplied that by 59.1m to get 20.186 kJ. The thing I am not sure how to figure out is how much work is required to pull him up at 2.07 m/s. Because anything greater than 20.186kJ would just pull him up, but not necessarily at 2.07 m/s. Also this answer alone counts as the right answer, but it can't be exactly right because its hasn't taken into account the desired velocity right?
