A 0.3-kg block is placed against a rotating hollow cylinder of inner radius = 0.7 m. The cylinder rotates around the vertical axis with a constant angular velocity of 15 rad/s. For friction to prevent the mass from sliding down the wall, what is the minimum coefficient of static friction u between the mass and the wall? %3D R
