A train car is accelerating forward with an unknown acceleration. There is a small mass hanging from a string that is attached to the ceiling of the train car. Because the train is accelerating forward, the mass is angled backwards at 8.2 deg. From the vertical. What is the magnitude of the trains acceleration?
