A mass of 4 kg is initially moving in the +x direction and collides inelastically with a mass of 8 kg moving in the -x direction at 7 m/s. After the collision, both masses move in the +x direction at 4 m/s. How fast was the 4 kg moving before the collision in m/s?

Aboxcar traveling at 12 m/s approaches a string of 5 identical boxcars sitting stationary on the track. the moving boxcar collides and links with the stationary cars and they all move off together along the track. what is the final speed of the cars immediately after the collision? (you may take the mass of each boxcar to be 18,537 kg.)
