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:

The work done is 1000 J

Step-by-step explanation:

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+

W=10×9.8×10+

×10×2×2

W=980+20

W=1000J

Hence, the work done is 1000 J
