Question

State the law of conservation of momentum. Derive
it by using Newton's third law of motion

Answer 1

Answer:

Applying Newton's third law, these two impulsive forces are equal and opposite i.e. If the time of contact is t, the impulse of the force F21 is equal to the change in momentum of the first object. The impulse of force F12 is equal to the change in momentum of the second object.
