A 499 g air-track glider attached to a spring withspring constant 13.4 N/m is sitting at rest on a frictionless airtrack. A 219 g glider is pushed toward it from the far end of thetrack at a speed of 140.1 cm/s. It collides with and sticks to the499 g glider.
What is the amplitude of the subsequent oscillations?
What is the period of the subsequent oscillations?
