Newton's third law gives the relationship between interacting forces between the two objects but does not give the magnitude of force. Law of Conservation of Momentum
Two objects of masses 100 g and 200 g are moving along the same line and direction with velocities of 2 ms– 1 and 1 ms – 1 , respectively. They collide and after the collision, the first object moves at a velocity of 1.67 ms – 1 .
