Question

A body of mass 10kg is raised from certain depth. By the time it is raised by 10m,if its velocity is 2ms inverse,work done during this time is​

Answer 1

Answer:

Given that,

Mass of body m=10kg

Height from depth h=10m

Velocity v=2m/s

Now,

Work done =   work done to change in P.E + work done in providing K.E to body

 W=mgh+21mv2

 W=10×9.8×10+21×10×2×2

 W=980+20

 W=1000J

Hence, the work done is 1000 J
