A 5.0 kg mass with an initial velocity of 4.0 m/s in the +x direction collides with a 4.0 kg mass with an initial velocity of 3.0 m/s in the x direction. After the collision, the 5.0 kg mass has a velocity of 1.2 m/s in the +x direction. What is the magnitude of the velocity of the 4.0 kg mass after the collision? (Hint: momentum is conserved, but energy is not.)
