A car of 600kg mass was moving 0.2 m/s^2 accelaration. the car then hits a pickup of 400kg after 60 sec. After collision they move with a velocity of 7.2 m/s^1
a. Find the applied force of 1st car
b. does the stem obey law of conservation? explain mathematically.

As we know that momentum is nothing but product of mass and velocity. Let us substitute the given values.
Given that mass of the car as 600 kg and velocity as 10 m/sec.
Hence momentum of the car is P=600×10=6000kgm/sec. We have mass of the scooter as 80 kg where as velocity is 50 m/sec.
Hence momentum is P=80×50=4000kgm/sec.
As momentum of car is more we need more force to stop the car.
