2) A 654 kg SmartCar initially traveling at 7.40 m/s collides with a 987 kg VW Bug that is moving at -2.60 m/s. These velocities are measured in what we will call the “regular” frame: the frame of reference that is at rest with respect to the roadway. We can exclude external forces acting during the collision (momentum is conserved).Now treat this collision as being elastic.

A) What is the total momentum of the system before the collision?

B) What is the velocity of the center of mass for this system?

C) What are the velocities of the cars in the COM frame before the collision?

D) What are the velocities of the cars in the COM frame after the collision?

E) What are the velocities of the cars in the “regular” frame after the collision?

F) Use the velocities found in part E to confirm that momentum is indeed conserved.
