A 494 g air-track glider attached to a spring with spring constant 7.5 N/m is sitting at rest on a frictionless air track. A 210 g glider is pushed toward it from the far end of the track at a speed of 146.5 cm/s. It collides with and sticks to the 494 g glider.
(a) What is the amplitude of the subsequent oscillations?
(b) What is the period of the subsequent oscillations?
