2. If two bodies of equal masses move with uniform velocity of 'v' and '3v', what will be the ratio of their kinetic energies?

Solution: Mass of first body = m
Velocity of the first body = v
Mass of second body = m
Velocity of second body = 3v

The ratio of kinetic energies of the two bodies = (kinetic energies of first body)/(kinetic energies of second body)
=((1/2)mv2)/((1/2)m(3v)2)
=1/9
Therefore the ratio of the kinetic energies = 1:9
