Question

A girl of mass 50 kg she runs 40 m in 40 sec . Find the power of the girl ​

Answer 1

Answer:

power = work / time

we know that work = force X displacement

therefore power = 50 X 9.8 X 40/ 40

power = 490 W

or power = 500W if u take g value 10 m/s²

Answer 2

Answer:

500

Explanation:

p =mgh/t

p=50×40×10/40

= 500
