A heavy flywheel is accelerated (rotationally) by a motor that provides constant torque and therefore a constant angular acceleration a. The flywheel is assumed to be at rest at time t-0 in Parts A and B of this problem Part C Assume that the motor has accelerated the wheel up to an angular velocity ay with angular acceleration a in time f. At this point, the motor is turned off and a brake is applied that decelerates the wheel with a constant angular acceleration of -5a. Find t₂, the time it will take the wheel to stop after the brake is applied (that is, the time for the wheel to reach zero angular velocity) Express your answer in terms of some or all of the following: w, a, and ₁. ▸ View Available Hint(e) VG] ΑΣΦΑ ?
