At the instant when θ = 30°, the horizontal guide is given a constant upward velocity v = 2 m/s. For this instant calculate the force N exerted by the fixed circular slot and the force P exerted by the horizontal slot on the 0.5-kg pin A. The width of the slots is slightly greater than the diameter of the pin, and friction is negligible.
