A coin is placed 34 cm from the center of a horizontal turntable, initially at rest. The turntable then begins to rotate. When the speed of the coin is 120 cm/s (rotating at a constant rate), the coin just begins to slip. The acceleration of gravity is 980 cm/s^2. What is the coefficient of static friction between the coin and the turntable?

A record turntable is rotating at 33 1/2 rev/min. A watermelon seed is on the turntable 9.4 cm from the axis of rotation. (a) Calculate the acceleration of the seed, assuming that it does not slip. (b) What is the minimum value of the coefficient of static friction between the seed and the turntable if the seed is not to slip? (c) Suppose that the turntable achieves its angular speed by starting from rest and undergoing a constant angular acceleration...
Fly and TurnTable
A fly sits on a rotating turntable. The turntable starts at rest and slowing increases (rotational) speed until the fly flies off. The fly is a distance 0.47 m from the center of the turntable. The fly slides off of the turntable when the turntable is rotating at 0.62 revolutions/second. What is the coefficient of static friction between the fly and the turntable?Please show all equations used and explain.
