Suppose one of the three students in Guided Example 7.6 stops pushing the car after 6.00 seconds. In this case, the force exerted on the car is 305 N for the first 6.00 seconds and 215 N for the second 6.00 seconds.

(a) What is the final momentum of the car?
(b) What is the final speed of the car?

Answer :

The final momentum is 250 newton.

What is momentum?

Momentum is the result of a particle's mass and velocity. Being a vector quantity, momentum possesses both magnitude and direction. According to Isaac Newton's second equation of motion, the force applied on a particle is equal to the time rate of change of momentum.

According to Newton's second law, if a particle is subjected to a constant force for a specific amount of time, the result of the force and time (referred to as the impulse) is equal to the change in momentum.

On the other hand, a particle's momentum represents the length of time needed for a consistent force to bring it to rest.

Therefore, The final momentum is 250 newton.
