1. A kinematics track in your lab is almost frictionless. Suppose a toy car weighs 0.5 kg and is attached to a spring (k=10 N/m). Another toy car weighing 0.25 kg moving with 1.2 m/s collides with the first toy car. Both cars are now moving back and forth together forming a new spring mass system. Find the maximum displacement of the system from the mean position and its frequency. Include all intermediate steps in your calculations. No points will be awarded if you only submit the final answer. (Hints: Review important concepts from conservation of energy/momentum & Waves) (6 points)
