Acar traveling 25 m/s to the north collides with a car traveling 15 m/s to the south. each car has a mass of 1100 kg. if the system is defined as the two cars, what is the change in momentum of the system due to the collision? a. 27,500 kg*m/s b.16,500 kg*m/s c.44,000 kg*m/s d. 0 kg*m/s

The change in momentum of the system due to the collision is 0 kg-m/s.

Explanation:

It is given that,

Initial velocity of car 1, (north)

Initial velocity of car 2, (south)

Mass of each cars,

It may be the case of elastic collision, such that they will exchange their velocities. So, the final speed of both the cars will be :

Final velocity of car 1, (south)

Final velocity of car 2, (north)

The change in momentum of the system due to the collision is equal to the final momentum minus initial momentum. So, it is equal to 0 kg-m/s. Hence, the correct option is (d) " 0 kg-m/s".                                                                                      

e

explanation:

there is no change in the electric potential energy as it is in rest on both conditions.
