Acylinder is rotating about an axis that passes through the center of each circular end piece. the cylinder has a radius of 0.0700 m, an angular speed of 88.0 rad/s, and a moment of inertia of 0.850 kg · m2. a brake shoe presses against the surface of the cylinder and applies a tangential frictional force to it. the frictional force reduces the angular speed of the cylinder by a factor of two during a time of 4.40 s.(a) find the magnitude of the angular deceleration of the cylinder. rad/s 2 (b) find the magnitude of the force of friction applied by the brake shoe. n
