1. The problem statement, all variables and given/known data A ferryboat sails between towns directly opposite each other on a river, moving at speed v_actual relative to the water. a) Find an expression for the angle it should head at if the river flows at speed v_river. b) What is the significance of your answer if v_river > v_actual? 3. The attempt at a solution a) v_effective = v_actual + v_river v_effective = hypotenuse, v_river = opposite, v_actual = adjacent Θ = arctan ( v_river/v_effective) b) How is it possible for the adjacent to be > than the hypotenuse?
