We use the definition of pressure to write , where in polar coordinates, and since the pressure is uniformly distributed, . Making this substitution for , we can find the total free torque due to friction (eq. (5.8)).

Since we are approximating the BoS as a circle, , and the magnitude of the total free torque due to kinetic friction is

so

Now that we have an expression for , we can find the rotational acceleration (which will be constant since τ is constant), and then use kinematics to find and the number of revolutions before stopping.
