A man walks along a straight path at a speed of 6 ft/s. A searchlight is located on the ground 24 ft from the path and is kept focused on the man. At what rate is the searchlight rotating when the man is 10 ft from the point on the path closest to the searchlight? Solution We draw the figure below and let x be the distance from the man to the point on the path closest to the searchlight. We let 0 be the angle between the beam of the searchlight and the perpendicular to the path. 24
