A 200-g disk sits on a horizontally rotating turntable. The turntable makes 1.5 revolutions each second. The disk is located 5 cm from the axis of rotation of the turntable. a) What the frictional force acting on the disk? b) If the coefficient of static friction between the disk and the turntable u; = 0.64 what the maximum distance from the disk to the axis of rotation where the disk can stay without sliding off the turntable? |
