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
