physics 101 chapter 9 question (part C only)

At t=0 spinding whel has an angilar velocity of 30.0rad/s. It has a conatant Fion then on, it torns tirough an angle 405 rad as it coasks to a slop at constant angulat acceleration: Part A Though what fots anglo did the wheel sum between t=0 and the fime it ithepod? Express yoer answer in radians. Part B At what time dd it slop? Express your answer in seconds. Correct reoked for this part Partc Express yosir answer in rabisna per second squared
