Two cars collide with each other. Before the collision, one car (m = 1300 kg)
is going north at 30 m/s and the other car (m = 900 kg) is going south at 15
m/s. What is the momentum of the system made up of the two cars after the
collision?

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

answer: b.

explanation:

god i hope this !
