22.What happens to the velocity of a light body when it undergoes an elastic collision in one dimension with a very heavy body at rest? [A] its velocity becomes twice [B] it rebounds with twice of its own velocity [C] it rebounds with its own velocity [D] it stops and comes to rest Show Answer
Notes: The heavy body keeps on moving with the same velocity when it undergoes an elastic collision in one dimension with a very light body at rest. Note: the body at rest starts moving with double the initial velocity of the heavy body.
