A 1200 kg truck is rear-ended by an 800 kg car. Before the collision, the car is traveling at 30 m/s and the truck is going

20 m/s. After the collision the car is traveling 23 m/s. If

momentum is conserved, how fast is the truck traveling?

Use units in ALL calculations.

First, label the quantities as shown in the diagram:

m1 = m2 =

u1 = u2 =

v1 = v2 =

1.) What is the momentum of the car before the collision?

2.) What is the momentum of the truck before the collision?

3.) What is the momentum of the car after the collision?

4.) What is the momentum of the truck after the collision?
