2 A grinding wheel powered by electricity is rotating at 66.6 rad/s when initially undergoes constant angular acceleration of 4.3 rad/s² until th electricity is cut off after 12.2 s. From then on, the rotation of the whe slowed down until it eventually come to a stop. If the wheel has turne a total of 414 rev during the whole course of its motion, what is the magnitude of the angular acceleration of the wheel as it slowed down O 1.71 radians per seconds squared 24.0 radians per seconds squared O4.83 radians per seconds squared 5.46 radians per seconds squared
