the sail area-displacement ratio S is given by S= 16A/d^2/3, where A is the sail area (ft^2) and d is the displacement (lb). S measures the amount of power available to drive a sailboat. Ratios range from 24 to 35, with a high ratio indicating a powerful boat. Find S for the sailboat, which has a displacement of 1400 tons, a sail area of 42400 ft^2, and 49 guns. What is the sail area-displacement ratio S = ?
