⏯️⏯️when two or more body act on another, there total momentum remain constant or conserved provide no external force acting on it.
⏯️⏯️ let us now consider two bodies a truck and a car moving on a straight line with initial velocity u1 and u2 having mass M1 and M2 respectively . suppose ( a) u1 > u2. at the time of collision the truck exert a force F1 on the car. hence, the velocity of car changes from v1 to V2.
hence acceleration produced in car will be equal to
force F1 exerted by truck on car will be
at the same time car also exert a force f 2 on the truck

according to Newton's third law of motion
F1 = -F2
