A platform is rotating at an angular speed of 1.9 rad/s. A block is resting on this platform at a distance of 0.33 meter from the axis. The coefficient of static friction between the block and the platform is 0.77. Without any external torque acting on the system, the block is moved toward the axis. Ignore the moment of inertia of the platform and find the smallest distance from axis at which block can be relocated and still remain in place as the platform rotates.
