A rotating cylinder of mass 3.2 kg and radius 30 cm is spinning
around the vertical axis that goes through its center at a rate of
31 rpm (revolution per minute). The cylinder is then slowed down to
a halt by applying a 10 N force along the radial direction. If the
coefficient of kinetic friction in this break mechanism is 0.43,
calculate how much time it takes to stop the cylinder.
