Answer #1

To solve this problem we will be using the basic idea of Conservation of Momentum and Kinetic Energy.

Therefore the final velocity of the first and second body is -15m/s and 0 m/s respectively.

The Kinetic Energy of the body is  1125 J

While stuck at a railroad crossing, you notice a full train car (m1 = 9000kg) is moving to your left with a speed of 9m/s. Two seperated empty train cars (m2 & m3 = 3000kg each) are on the same track moving to the right, each with a speed of 3m/s. There are two succesive collisions. First m1 and m2 hit and stick together. That pair (m1 & m2) then runs into m3. In this second collision, the air bag...
