A flywheel has a constant angular deceleration of 2.5 rad/sec^2. I need to ... 1. find the angle through which the flywheel turns as it comes to rest from an angular speed of 117 rad/sec. 2. Find the time required for the flywheel to come to rest. So i used the formula w^2=wo^2+2a(theta) since w^2 is 0, that would make theta 0, which is not possible.
