Bill forgets to put his car in park and it starts rolling west. When it is moving at a speed of 3.5 m/s, it collides with Tanya’s car, which is moving at a speed of 2 m/s east. Bill’s car bounces backward (to the east) at a speed of 2m/s. Bill’s car has a mass of 900kg, and Tanya’s car has a mass of 1100kg.

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

b) What is the total momentum of the system after the collision?

c) What is the velocity of Tanya’s car after the collision?
