A body of mass m moving with velocity 
makes a head-on collision with another body of mass 2m which is initially at rest. The loss of kinetic energy of the colliding body (mass m) is
A
of its initial kinetic energy B
of its initial kinetic energy C
of its initial kinetic energy D
of its initial kinetic energy
Text Solution
Verified by ExpertsThe correct answer is:
C
Loss of kinetic energy of the colliding body,
Therefore, loss of kinetic energy is 
of its initial kinetic energy.
