we know,
any moving body have must exist kinetic energy .
e.g kinetic energy = 1/2mv^2 =16 × 10^5
1/2 x 200 x v^2 = 16 x 10^5
100 x v^2 = 16 x 10^5
v^2 = 16 x 10^3
v = 40√10 m/s

given m=200kg
energy=16*105J
16*105=1/2*200v*v
=100v^2
v^2 =16*105/100
=16.8
v=4.09m/s
________

l think there is some mistake in question....watz the actual energy possesd by objct due to itz motion?
