2 A grinding wheel powered by electricity is rotating at 70.3 rad/s when it initially undergoes constant angular acceleration of 4.75 rad/s until the electricity is cut off after 12.6 s. From then on, the rotation of the wheel slowed down until it eventually come to a stop. If the wheel has turned a total of 364 rev during the whole course of its motion, what is the magnitude of the angular acceleration of the wheel as it slowed down? 5.58 radians per seconds squared 17.7 radians per seconds squared 8.27 radians per seconds squared 2.16 radians per seconds squared
