Two cars are driving along Robinson Street during an ice storm when they hit a patch of ice. The car in front is traveling at a speed of 8.5 m/s when it starts sliding and the car in back is traveling at a speed of 16.0 when it starts sliding. The mass of the front car is larger than the mass of the back car: Mfront = 2 Mback.
When the back car hits the front and the bumpers lock, how fast will the two cars be moving?
