A certain power supply generates a voltage waveform that can be characterized as a cosine wave V_m cos(omega t + psi) having a frequency of 17.89 Hz. If the supply delivers a maximum power of 475 W to a 12-Ohm load and the voltage reaches a maximum at t = 16.59 ms, what are V_m, omega, and psi? Round answers to two decimal places. V_m = V omega = rad/s phi = degree
