1. A car of mass m1 stopped at a traffic light is rear-ended by a car with mass m2. The cars become entangled. The second car was moving at vi = 30.0 m/s before the collision. What kind of collision is this?



2. A car of mass m1 stopped at a traffic light is rear-ended by a car with mass m2. The cars become entangled. The second car was moving at vi = 30.0 m/s before the collision. What are the quantities conserved in this collision?



3. A car of mass m1 stopped at a traffic light is rear-ended by a car with mass m2. The cars become entangled. The second car was moving at vi = 30.0 m/s before the collision. What is the velocity of the entangled cars after the collision in terms of masses m1 and m2, and the initial velocity of the second car?



4. A car of mass m1 stopped at a traffic light is rear-ended by a car with mass m2. The cars become entangled. The second car was moving at vi = 30.0 m/s before the collision. What are the initial kinetic energies of the two cars, if m1 = 2500 kg and m2 = 1000 kg?



5. A car of mass m1 stopped at a traffic light is rear-ended by a car with mass m2. The cars become entangled. The second car was moving at vi = 30.0 m/s before the collision. What are the initial linear momenta of the two cars if m1 = 2500 kg and m2 = 1000 kg?



6. A car of mass m1 stopped at a traffic light is rear-ended by a car with mass m2. The cars become entangled. The second car was moving at vi = 30.0 m/s before the collision. What is the kinetic of the system after the collision if m1 = 2500 kg and m2 = 1000 kg?
