Answer:

Please check the question again

Because in kinetic energy there are only mass and speed

Hence kinetic energy = 1/2× mass× (speed)^2

Answer:

25000

Explanation:

Energy = 250J

mass = 20 kg

hight = 5m

work done = force x displacement

We want to find force to find W.D

force = Energy x Mass

         = 250 x 20

         =5000

W.D = 5000 x 5

       = 25000

ans

      W.D = 25000J
