1. A 500g glider on an air track is at rest, and is attached to a spring with a spring constant of 10 N/m. A 250g glider moving 120 cm/s collides with and sticks to the 500g glider. What is the amplitude and period of the resulting oscillations?
2. Consider again the glider system from problem 1. The only change is that in this problem, the 250g glider bounces off the 500g glider elastically and has a final velocity of - 40 cm/s (that is, in the opposite direction). What is the amplitude and period of the oscillations of the 500g glider in this case?
