Askier of mass 71 kg is pulled up a slope by amotor-driven cable. the acceleration of gravity is 9.8 m/s2.how much work is required to pull him 62 mup a 31◦slope (assumed to be frictionless) ata constant speed of 2.58 m/s? answer in units of kj

Work done will be 22216.894 J

Explanation:

We have given mass of the skier m = 71 kg

Acceleration due to gravity

Slop is given as

Distance d = 62 m

So vertical distance

We know that work done is given by
