Asked by Ashley
A skier of mass 71 kg is pulled up a slope by a motor-driven cable.
The acceleration of gravity is 9.8 m/s2. How much work is required to pull him 64.6 m up a 33.8 slope (assumed to be frictionless) at a constant speed of 2.53 m/s?
Answer in units of kJ

work= force*distance
= mg*sin33.8*distance
YOu can figure power also
power= work/time= force*velocity/distance
= 71*g*Sin33.8*2.53 watts.
= mg*sin33.8*distance
