Accelerometer the system shown in Fig. 5.76 can be used to measure 1he acceleration of 1he system. An observer riding on the platform measures the angle θ that the 1hread supporting the light ball makes with the vertical. There is no friction anywhere.
(a) How is θ related to the acceleration of the system?
(b) If m, = 250 kg and m2 = 1250 kg, what is θ?
(c) If you can vary m, and m2, what is the largest angle θ you could achieve? Explain how you need to adjust m, and m2 to do this.
