Unless otherwise stated, in the following problems we assume that the gravitational force is constant with g = 9.81 m/sec² in the MKS system and g = 32 ft/sec² in the U.S. Customary System.

In Problem 21 it is observed that when the velocity of the sailboat reaches 5 m/sec, the boat begins to rise out of the water and “plane.” When this happens, the proportionality constant for the water resistance drops to b0 = 60 N-sec/m. Now find the equation of motion of the sailboat. What is the limiting velocity of the sailboat under this wind as it is planing?
