Question

Nitin weighs 50kg, climbed 45 steps each of height 5cm. Calculate the work done by Nitin in joule unit. (g=10m/s2)

GIVE CORRECT ANSWER OR IT WILL BE REPORTED ​

Answer 1

Answer:

Given that,

Mass of boy, m=50kg

Potential energy at a height of 45 steps , P=mgh=50×10×45×0.15=3375J

Time taken to climb 45 steps , t=9secs

Power of boy =

t

P

=

9

3375

=375 W
