The coefficient of friction between a certain brass block and a large revolving turntable is μ = 0.24. The turntable is rotating at 33 1/3 rev/min.
1) What is the period of rotation of the turntable?
s
2) What is the maximum acceleration of the block?
m/s/s
3) How far from the axis of rotation can the block be placed before it slides off the turntable?
m
