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 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.
