일반물리학 1 — Rotation: Problem 27

27 A seed is on a turntable rotating at \(33\frac{1}{3}\) rev/min, 6.0 cm from the rotation axis. What are (a) the seed’s acceleration and (b) the least coefficient of static friction to avoid slippage? (c) If the turntable had undergone constant angular acceleration from rest in 0.25 s, what is the least coefficient to avoid slippage?
