Two cars collide with each other in a crash test (under controlled conditions and with crash dummies aboard). Before the collision, the red car is traveling at 14 m/s in the negative x direction (refer to the axes included above). The silver car is traveling in the positive x direction at 20 m/s. The red car has a mass of 1600 kg and the silver car has a mass of 1800 kg. a) What is the total momentum in the x-direction of the two cars before the collision? b) What is the total momentum in the y-direction of the two cars before the collision? c) What is the total momentum in the x-direction of the two cars after the collision?

Two objects collide head-on (see figure below). The first object is moving with an initial speed of v1i = 8.09 m/s and the second object is moving with an initial speed of v2i = 10.00 m/s.
