A wheel is rotating counter clockwise initially at an angular speed of 3.50 rad/s. It decelerates over a 4.0-s interval and stops after making 2 turns (1 Turn=2pi radians). a) What is its angular acceleration? c) If it keeps the same angular acceleration, how long would it take to start going with 3.5 rad/s clockwise?
