25. Construction A winch at the top of a 12-meter building pulls a pipe of the same length to a vertical position, as shown in the figure. The winch pulls in rope at a rate of - 0.2 meter per second. Find the rate of vertical change and the rate of horizontal change at the end of the pipe when y = 6 meters, ds dr = -0.2 sec (x, y) 13 ft 12 ft 12 m - 3 Nor drawn to meals Figure for 25 Figure for 2629 Sports A baseball diamond has the shape of a square with sides 90 feet long (see figure).
