A boat crossing a wide river moves with a speed of 18.0 km/h relative to the water. The water in the river has a steady speed of 8.00 km/h due east relative to the earth. a) If the boat heads due south, determine the speed of the boat relative to an observer standing on the shore. km/h 9. b) What is the angle made between the velocity of the boat relative to the observer and the south direction? 10. c) At what angle against the steam must the boat be headed with respect to the south direction in order for it to proceed south as seen by the observer on the shore?
