A skier of mass 70.0 kg is pulled up a slope by a motor-driven cable.

How much work is required to pull the skiera distance of 60.0m up a 30 degree slope (assumed frictionless) at a constant speed of 2.00 m/s?

2. Relevant equations

W=F (delta)r cos(theta)

3. The attempt at a solution

(delta)r= 60.0m

(theta)=30.0 degrees

Force=60sin30=30 J

Is this the correct start?
