The force exerted by the wind on a sailboat is approximately perpendicular to the sail and proportional to the component of the wind velocity perpendicular to the sail. For the 850-kg sailboat shown in the figure below, the proportionality constant is - (550 ) "wind N Fsail %3D m/s Water exerts a force along the keel (bottom) of the boat that prevents it from moving sideways, as shown in the figure. Once the boat starts moving forward, water also exerts a drag force backwards on the boat, opposing the forward motion. If a 18-knot wind (1 knot = 0.514 m/s) is blowing to the east, what is the initial acceleration of the sailboat? m/s2 F F keel 30° -E
