A ball of mass m moving with velocity v collides head-on which the second ball of mass m at rest. I the coefficient of restitution is e and velocity of first ball after collision is $v_{1}$ and velocity of second ball after collision is $v_{2}$ then

$v_{1} = \frac{(1 - e) u}{2}, v_{2} = \frac{(1 + e) u}{2}$

$v_{1} = \frac{(1 + e) u}{2}, v_{2} = \frac{(1 - e) u}{2}$

$v_{1} = \frac{u}{2}, v_{2} = - \frac{u}{2}$

$v_{1} = (1 + e) u, v_{2} = (1 - e) u$
