Dr. baker has a nice collection of old-style vinyle records. to listen to his records, dr. baker uses a turntable, which is rotating at 33 1/3 rev/min. during a moment of boredom, dr. baker put a coffee bean on his turntable 7.0 cm from the axis of rotation.
(a) calculate the acceleration of the coffee bean, assuming that it does not slip m/s^2.
(b) what is the minimum value of the coefficient of static friction between the bean and the turntable if the bean does not slip?
(c) suppose that the turntable achieves its angular speed by starting from rest and undergoing a constant angular acceleration for 0.75 s. calculate the minimum coefficient of static friction required for the bfean not to slip during the acceleration period
