Question:

On a frictionless, horizontal air track, a glider oscillates at the end of an ideal spring of force constant 2.50 N/cm. The graph in Fig. 13.31 shows the acceleration of the glider as a function of time. Find
(a) The mass of the glider;
(b) The maximum displacement of the glider from the equilibrium point;
(c) The maximum force the spring exerts on the glider.
