Momentum Calculations
1. A VW at 30 mph rear-ends a stationary Buick. 30 mph is 13.4 m/s. They lock bumpers and move off together after the collision. The mass of the VW is 750 kg and the Buick’s is 2,000 kg. What is their final velocity after the impact? (Change VW mass to 1000kg)

2.  Car A at 10 m/s collides with car B at rest. Each car has a mass of 1000 kg. The collision is inelastic. What is each of their final velocities?
Car A   vFinal = ________ m/s
Car B   vFinal = ________ m/s

(Change both masses to 2000kg)

3.. A 1930 Model A coupe (1050 kg) at 5m/s collides with a stationary 1930 sedan (1070 kg), and due to their spring steel bumpers, this collision is elastic. The coupe is stationary after impact. What is the final velocity of the sedan? (Change coupe mass to 1070kg and sedan mass to 1050kg)
