Two cars collide with each other. before the collision, one car (m = 1100 kg) is going north at 18 m/s and the other car (m = 1300 kg) is going south at 16 m/s. what is the momentum of the system made up of the two cars after the collision?

where is the photo and the answer choices?

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
