Linear momentum of first body = Linear momentum of second body. m1v1 / m2v2 = m2v2 / 4m1v2 = 1/2.

1. (a) K.E.1 = K.E.2
2. (b) 1/2 m1v1^2 = 1/2 m2v2^2
3. (c) v1 = 2 => v1 = 2v2
4. (d) All of the above

Correct answer: (c) v1 = 2 => v1 = 2v2

Solution

The given condition implies that the ratio of velocities is such that v1 = 2v2. This satisfies the relationship derived from the equality of linear momenta.
