Question

The momentum of a body of mass m moving at a velocity v is found to be p. What will be its momentum when its mass gets tripled and its velocity halved?

  1. 2p
  2. 1 third
p
  3. 3 over 2p
  4. 2 over 3p

hintHint:

The momentum of a body of mass m moving at a velocity v is found to be p.the momentum will be 3 over 2p.

The correct answer is: 3 over 2p
