Question

A man weights 800 Newton and carries a load of 800 Newton upto height of 100 meter. Find work done and power in horse power.

Answer 1

Total weight = 500N+100N = 600N
Height = 4m
Time = 5s
Power = work done / time taken
= (force * displacement) / time taken. ( because w = f * s)
= 600 *4/5
= 2400/5
= 480 watt
