A load of mass 10kg is raised through a height of 15m from the ground where it was initially at rest when it at that height it has velocity of 20m/s. find the work done.

Answer 1

the energy of the load (equivalent to work) is gravitational potential plus kinetic

work = m g h + 1/2 m v^2 = (10 * 9.8 * 15) + (1/2 * 10 * 20^2)
... answer is in Joules

Answer 2

I didn't get the answer using it...and it seems to be wrong...

Answer 3

Answer is wrong I have used same method
