Jerome solves a problem using the law of conservation of momentum. what should jerome always keep constant for each object after the objects collide and bounce apart?
a-velocity
b-mass
c-momentum
d-direction

The question is based on the fundamental principle of law of conservation of momentum.

As per the question, the two bodies collide with each other and bounce apart.

As per the law of conservation of momentum, the momentum of an isolated system always remains constant.

Here, the two bodies constitute a system. Hence, the momentum will be conserved for the system.

The momentum of individual bodies may not be conserved as their direction and velocity must have changed during that collision. But, the mass of a body is always constant for a non-relativistic motion. The mass of each bodies before collision will be equal to the mass after collision.

Hence, the correct answer to the question is b) Mass.

B mass
