Consider the following statements A and B and identify the correct answer A. In an elastic collision, if a body suffers a head on collision with another of same mass at rest, then the first body comes to rest while the other starts moving with the velocity of the first one. B. Two bodies of equal mass suffering a head on elastic collision merely exchanges their velocities

Options
