A 0.50 kg air track glider is attached to the end of the track by a spring that has a constant of 20.0 N/m. The glider is compressed 15.0 cm from equilibrium and released at t = 0, so that it oscillates back and forth on the friction less air track surface. What is its magnitude of acceleration at a time equal to 1/8th of the oscillator' *****?
(A) 3 m/s2
(B) 3√2 m/s2
(C) 6 m/s2
(D) 3√3 m/s2
