The pin P is constrained to move in the slotted guides which move at right angles to one another. At the instant represented, A has a velocity to the right of 0.2 m/s which is decreasing at the rate of 0.75 m/s each second. At the same time, B is mov- ing down with a velocity of 0.15 m/s which is de- creasing at the rate of 0.5 m/s each second. For this instant determine the radius of curvature p of the path followed by P. Is it possible to also determine the time rate of change of p? B A
