An air-track glider is attached to a spring on a frictionless horizontal surface. The air-track glider is pulled to the right and released from rest at t = 0 s. If the air-track glider reaches a maximum speed of 43.9 cm/s and oscillates with a period of 2.50 s, what is the air-track glider's acceleration at t = 0.950 s?
