Question

state law of conservation and prove by using newtons second law​

Answer 1

Explanation:

According to Newton's second law of motion, External force = Rate of change of momentum. Hence in the absence of an external force, the total momentum of a group of objects remains unchanged or conserved during the collision. This is the law of conservation of momentum.

Answer 2

Answer:

F12 is the force exerted by the m1 during the collision on m2. F21 is the force exerted by the m2 during the collision on m1. Therefore, F12 = F21. There is a change in the velocity of these balls after the collision which is given as: P1f = m1v1.
