A car of mass 1000 kg is moving at 25 m/s. It collides with a car of mass 1200 kg moving at 30 m/s. When the cars collide, they stick together,
a. What is the total momentum of the system before the collision? (8 point)

Explanation:

As momentum is a vector, we cannot tell for sure.

It will be bracketed between a maximum of

1000(25) + 1200(30) = 61000 kg•m/s

if both cars are moving in the same direction before collision

and a minimum of

1200(30) + 1000(-25) = 11000 kg•m/s

if the cars are in for a head on collision.

It could have a magnitude anywhere between these two limits for a collision angle 0<θ<180°
