The flywheel is assumed to be at rest at timet 0 in Parts A and B of this problem.at201Previous AnswersSubmitCorrectPart CAssume that the motor has accelerated the wheel up to an angular velocity wi with angular acceleration a in time t1. At this point, the motor is turned off and abrake 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 isapplied (that is, the time for the wheel to reach zero angular velocity)Express your answer in terms of some or all of the following: w1, a, and t1View Available Hint(s)V ΑΣφ?Et2SSubmitProvide FeedbackNextQuestion
