A small block B fits inside a slot cut in arm OA that rotates in a vertical plane at a constant rate. The block remains in contact with theend of the slot closest to A and its speed is 1.4 m/s for 0 ≤ θ ≤ 150°.Knowing that the block begins to slide when θ = 150°, determine thecoefficient of static friction between the block and the slot.
