A 50.0 g toy car on a frictionless surface moving at constant velocity (moving 1.0 m in 0.25 seconds) collides with and bounces off of a stationary 100.0 g toy car. The 50.0 g glider bounces back (moving 1.0 m in 2.0 seconds) and the 100.0 g glider continues moving forward (going 1.0 m in 0.75 seconds).

a) Is momentum conserved in this collision? Show all of the work required to determine this.

b) Is the collision completely elastic? Explain in terms of the calculated values for kinetic energy before and after the collision.
