Question:
Consider a small sailboat with a triangular sail of height 10 m and width at the base of 5.0 m.
(a) Assuming a wind speed of 15 mi/h relative to the boat and a wind direction perpendicular to the sail, estimate the force exerted by the wind on the sail.
(b) If the sailboat is moving with a constant speed, what is the drag force due to the water?
(c) Suppose the speed of the wind relative to the boat is doubled to 30 mi/h. By what factor does the speed of the boat relative to the water increase?
