Question
A body of mass m1 moving with velocity u collides elastically with mass m2 at rest. Find the fractional energy transferred to mass m2 after collision. |
Solution
Velocity of mass m2 after collision is given by,

Since initially mass m2 is at rest, therefore kinetic energy transferred to mass m2 is equal to the kinetic energy of mass m2 after the collision.
Therefore,
Fractional energy transferred is,
