Two bodies of equal mass undergo a one-dimensional elastic collision, with one initially at rest. After the collision:

1. A both come to rest
2. B they exchange velocities Correct answer
3. C they move together
4. D the moving body rebounds at original speed

Solution

For equal masses in 1D elastic collision, velocities are simply exchanged.
