Sign up for free to discover our expert answers. When a moving object strikes another body, be it moving or resting, the collision is said to be elastic so long as the net loss of momentum and kinetic energy during the collision is observed to be zero. (0.22 + m_2)m_2 = (0.22 - m_2)^2\\ After the collision, only one object is moving, so the total momentum is equal to this object's momentum: By conservation of momentum, these two quantities must be equal. a) They have the same mass.
