On a frictionless, horizontal air track, a glider oscillates at the end of an ideal spring of force constant 2.30 N/cm. The graph in the figure shows the acceleration of the glider as a function of time.
Find the mass of the glider.
Find the maximum displacement of the glider from the equilibrium point.
Find the maximum force the spring exerts on the glider.

m=(kT^2)/(4pi^2) T=1 full period. k=230
A=(a_max(T^2))/(4pi^2)=meters*100=cm
F_max=kA k=2.30N/cm
