A heavy flywheel is accelerated by a motor that provides constant toque and therefore a constant angular acceleration a. It starts at rest at t = 0. a. Find the time, t1, it takes to accelerate the flywheel to w1. b. Find the angle 0, which the flywheel will have turned during the time it takes for it to accelerate from rest up to angular velocity w1. c. Assume that the motor has accelerated the wheel up to an angular velocity of w, with angular acceleration a in time t . At this point, the motor is turned off and a brake is applied such that there is a constant angular acceleration of -5 a. Find the time it will take for the wheel to come to a stop.
