At the instant when ? = 51?, the horizontal guide is given a constant upward velocity v0 = 1.2 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 0.35-kg pin A. The force N is positive if the pin contacts the inside of the circular track and the force P is positive if it contacts the bottom of the horizontal guide. The width of the slots is slightly greater than the diameter of the pin, and friction is negligible.
