1A.)A railroad car of mass 21700 kg moving with a speed of 3.36 m/s collides
and couples with another rail car of mass 41700 kg, moving in the same
direction with a speed of 1.34 m/s. What is the speed of the two coupled
cars after the collision?
1B.)A 0.455-kg ball traveling at 7.36 m/s west collides head on with a 1.01-kg
ball moving in the opposite direction at a velocity of 12.4 m/s. The 0.455-
kg ball rebounds at 15.4 m/s after the collision. Find the velocity of the
second ball. (use west as the positive direction)
