Question:

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

Options:

– 0.5 m/s and 0.3 m/s

0.5 m/s and – 0.3 m/s

– 0.3 m/s and 0.5 m/s

0.3 m/s and 0.5 m/s

Correct Answer:

0.5 m/s and – 0.3 m/s

Explanation:

The velocities will be interchanged because it's an elastic collision.
