Consider a drum of a clothing dryer that is turning at a rate of 1 revolution every second when you suddenly open the door of the dryer. You noticed that it took 28 seconds for the drum to completely stop. What is the angular speed (in rad/s) at the precise moment when you suddenly open the door of the dryer? rad/s Determine the deceleration (in rad/s*) of the drum. Assume constant deceleration. (Include the sign of the value in your answer.) rad/s2
