Work= force × displacement
work= (10×10)×5 =500 joules
power=work/time
power= 500/5=100
work= (10×10)×5 =500 joules
power=work/time
power= 500/5=100

To calculate the power of the man, we need to use the formula:
Power = Work / Time
First, let's calculate the work done by the man. The work done is equal to the force applied multiplied by the distance covered.
Since the man is pulling the bucket of water vertically upwards, the force applied is equal to the weight of the bucket of water. The weight is given by the formula:
Weight = mass * acceleration due to gravity
Weight = 10kg * 9.8m/s² (acceleration due to gravity)
Weight = 98N
The distance covered is given as 5m.
So, the work done by the man is:
Work = Force * Distance
Work = 98N * 5m
Work = 490J
Now, let's calculate the power:
Power = Work / Time
Power = 490J / 5s
Power = 98W
Therefore, the power of the man is 98 Watts.
