10. (a) State the law of conservation of momentum. Write its mathematical expression.
(b) A car and a truck are covering equal distance in equal intervals of time. Which has more
momentum and why?
(c) While playing a cricket match 2 batsman Rohan and Tanish collided while taking a run
and got entangled with each other. The masses of Rohan and Tanish were 40 kg and
60 kg respectively. If Tanish was running with velocity of 3 m/s and Rohan was running
with velocity of 4 m/s, find their velocity after they get entangled.

Answer:
Newton's third law states that for a force applied by an object A on object B, object B exerts back an equal force in magnitude, but opposite in direction. This idea was used by Newton to derive the law of conservation of momentum. ... B=m_{2}(v_{2}-u_{2}) (change in momentum of particle B)
