Question

a woman draws water from a well of 15 metre depth in 15 seconds if the mass of her bucket Drone is 10 kg calculate the power used by her

Answer 1

Work done = mgh
= 10 kg × 10 m/s² × 15 m
= 1500 Joule

Power = Work / Time
= 1500 Joule / (15 second)
= 100 Watt

[Note: I took value of g equal to 10 m/s² to make my calculations easy]

Answer 2

I hope it will help u
