A third listener is positioned along the positive y-axis. What is her y-coordinate if same wave front reaches her at the same instant it does the first two listeners.
At t = 0 a grinding wheel has an angular velocity of 27.0 rad/s. It has a constant angular acceleration of 32.0 rad/s2 until a circuit breaker trips at t = 2s. From then on, it turns by 432 rad as it coasts to a stop at constant angular accelerati..
