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 after the collision?

Momentum of the car after the collision:
p = m v = (800 kg)(23 m/s) = 18,400 kg·m/s (forward).
