Physics · System of Particles and Rotational Motion
Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: A body P having mass M moving with speed v has a head-on elastic collision with another body Q having mass m initially at rest. If m << M, body Q will have a maximum speed nearly equal to 2v after the collision. Reason R: During an elastic collision, both the total momentum and total kinetic energy are conserved. In the light of the above statements, choose the most appropriate answer:
