Question

A body of mass 5kg is pulled up a slope by a force of 30 N

1. Calculate the force of gravity acting on a body G = 10 m/s
2. Work Done by the force that is pulling the gravity
3. Work Done against the forced gravity

Please can you answer those Questions it will be of Great Help ​​

Answer 1

Answer:

(i) Work done in moving the block from = F × d

A to B = 200 N × 3m = 600 J

(ii) Gain in potential energy = mgh = 30 × 10 × 1.5 = 450 J.
