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. 24.67 m/s
What is the momentum of the car before the collision?
