A glider with mass m = 0.240 kg sits on a frictionless horizontal air track, connected to a spring with force constant k= 5.00 N/m. You pull on the glider, stretching the spring 0.130 m, and then release it with no initial velocity. The glider begins to move back toward its equilibrium position (x=0).
What is the speed of the glider when it returns to x=0?
What must the initial displacement of the glider be if its maximum speed in the subsequent motion is to be 3.00 m/s?
