On a smooth surface, a 0.140-kg toy car 1 at the velocity of 5.0 m/s collides
elastically with another 0.100-kg toy car 2 with a velocity of 3.0 m/s. The
velocities of the two toy cars are in the same direction. After the collision, toy
cars 1 and 2 keep moving in the same direction with toy car 1 having a velocity of
2.8 m/s. What is the velocity of toy car 2 after the collision? Show the steps on
how you arrived at your final answer. Are the momentum and kinetic energy of
the system conserved in this collision? Explain.
