Question

Two identical balls A and B having velocities of 0.5 m s^$-$1 and $-$0.3 m s^$-$1 respectively collide elastically in one dimension. The velocities of B and A after the collision respectively will be :

$-$0.5 m s^$-$1 and 0.3 m s^$-$1

0.5 m s^$-$1 and $-$0.3 m s^$-$1

$-$0.3 m s^$-$1 and 0.5 m s^$-$1

0.3 m s^$-$1 and 0.5 m s^$-$1
