Solution

The correct option is C less than
Kinetic energy is given by K.E = 12mv2

Momentum is defined as P = mv

Thus K.E = 12Pv2

P1 = M(greater mass) v
P2 = m v(greater velocity)
P2 = P1 = P

K1 = 12Pv

K2 = 12PV

SInce V>v, K2>K1
Therefore the kinetic energy of the heavier mass is less than the kinetic energy of the lighter mass.
