A record turntable is rotating at 33 1/3 rev/min. A watermelon seed is on the turntable 6.4 cm from the axis of rotation. (a) Calculate the acceleration of the seed, assuming that it does not slip. 0.78 Correct: Your answer is correct. m/s2 (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? 0.78 Incorrect: Your answer is incorrect. (c) Suppose that the turntable achieves its angular speed by starting from rest and undergoing a constant angular acceleration for 0.45 s. Calculate the minimum coefficient of static friction required for the seed not to slip during the acceleration period.
