Question1
A 575g air-track glider attached to a spring with spring constant 14.0 N/m is sitting at rest on a frictionless air track. A 225 g glider is pushed toward it from the far end of the track at a speed of 84.0 cm /s. It collides with and sticks to the 575g glider.
a. What is the amplitude of the subsequent oscillations?
b. What is their period?
Question2
