<div>2. If two bodies of equal masses move with uniform velocity of 'v' and '3v', what will be the ratio of their kinetic energies?<br />
<br />
Solution: Mass of first body = m<br />
Velocity of the first body = v<br />
Mass of second body = m<br />
Velocity of second body = 3v<br />
<br />
The ratio of kinetic energies of the two bodies = (kinetic energies of first body)/(kinetic energies of second body)<br />
=((1/2)mv2)/((1/2)m(3v)2)<br />
