Regard as two cars both moving eastward along a straight road. Car 1 is in facade of car 2. Car 1 has a mass of 1200 kg as well as a speed of 24 m/s. Car 2 has a mass of 1100 kg as well as a speed of 32 m/s. Regard as eastward to be the positive direction. Car 2 crashed with car 1. The two cars stick collectively and move off as one object. None of external eastward / westward forces act on either car. What is the sum momentum of the combination object consisting of the two cars stuck together after the collision?
