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

Options

A. `v_(1)=((1-e)u)/(2), v_(2)=((1+e)u)/(2)`
B. `v_(1)=((1+e)u)/(2), v_(2)=((1-e)u)/(2)`
C. `v_(1)=(u)/(2), v_(2)=-(u)/(2)`
D. `v_(1)=(1+e)u, v_(2)=(1-e)u`

Answer

A
