State work-energy theorem. The momentum of a body of mass 5 kg is 500 `kg*m*s^(-1)`. Find its kinetic energy.

Explanation

1st part:
2nd part: Mass of the body m=5kg , let the velocity of the body =v.
Momentum of the body `=mv=500 kg*m*s^(-1)`
So, velocity of the body `v= (mv)/(m)=(500)/5=100 m*s^(-1)`
Hence kinetic energy
`=1/2 mv^2=1/2xx5xx(100)^2=25000J=25kJ`
