37. ssm mmh Multiple-Concept Example 10 offers useful background for problems like this. A cylinder is rotating about an axis that passes through the center of each circular end piece. The cylinder has a radius of 0.0830 m, an angular speed of 76.0 rad/s, and a moment of inertia of 0.615 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 6.40 s. (a) Find the magnitude of the angular deceleration of the cylinder. (b) Find the magnitude of the force of friction applied by the brake shoe.

Question
37. ssm mmh Multiple-Concept Example 10 offers useful background
for problems like this. A cylinder is rotating about an axis that passes
through the center of each circular end piece. The cylinder has a radius
of 0.0830 m, an angular speed of 76.0 rad/s, and a moment of inertia of
0.615 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
6.40 s. (a) Find the magnitude of the angular deceleration of the cylinder.
(b) Find the magnitude of the force of friction applied by the brake shoe.
