Arecord turntable is rotating at 33 1/3 rev/min. a watermelon seed is on the turntable 6.1 cm from the axis of rotation. (a) calculate the acceleration of the seed, assuming that it does not slip. 7432 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? .0758 correct: your answer is correct. (c) suppose that the turntable achieves its angular speed by starting from rest and undergoing a constant angular acceleration for 0.20 s. calculate the minimum coefficient of static friction required for the seed not to slip during the acceleration period.
