1. The problem statement, all variables and given/known data Moving at its maximum safe speed, an amusement park carousel takes 12 s to complete a revolution. At the end of the ride, it slows down smoothly, taking 3.5rev to come to a stop. What is the magnitude of the rotational acceleration of the carousel while it is slowing down? 2. Relevant equations w2=wo2+2alpha theta 3. The attempt at a solution plug in and get -pi/144 rad/s2 is this right???
