146121 A motor cyclist wants to drive in horizontal circles on the vertical inner surface of a large cylindrical wooden well of radius \(8.0 \mathrm{~m}\) with minimum speed of \(5 \sqrt{5} \mathrm{~m} \cdot \mathrm{s}^{-1}\). The minimum value of coefficient of friction between the tires and the wall of the well must be - \((g=10\) \(\mathbf{m} \cdot \mathbf{s}^{-2}\) )
146123 A solid flywheel of mass \(20 \mathrm{~kg}\) and radius 120 \(\mathrm{mm}\) revolves at \(600 \mathrm{rpm}\). Find the total force that must applied by the brake so that the flywheel stop in 3 seconds. Given the coefficient of friction between the wheels and brake lining is 0.1 .
