A student parks their 1979 Cadillac Seville (mass = 2000-kilograms) atop a large hill. Unfortunately, they forget to set the brakes and the car begins to roll down the hill. It reaches a final velocity of 20 meters/second before running into a teacher's 1960 Volkswagen. If the VW has a mass of 1000-kilograms and was at rest before the collision, find the following: a. The momentum of the Cadillac before the collision: to b. The Caddy stops completely at impact, what is the speed of the VW after the collision? c. If the two cars are in contact with each other for 0.2-seconds, what is the magnitude of the force they exert on each other? after d. Instead of having an elastic collision, the two cars experienced an inelastic collision, what speed would the combined cars have?
