drag Force on a boat: The drag force F on a boat is jointly proportional to the wetted surface area A on the hull and the square of the speed s of the boat. A boat experiences a drag force of
220 lb. when traveling at 5 mi/h with a wetted surface area of 40 ft2. How fast must a boat be traveling if it has 28 ft2 of wetted surface area and is experiencing a drag force of 175 lb.?
