Hello, Could somebody please give me clues as to how to do this problem? A ship cruises forward at vs = 4 relative to the water. On deck, a man walks diagonally toward the bow such that his path forms an angle delta = 28 degrees with a line perpendicular to the boat's direction of motion. He walks at vm = 2 m/s relative to the boat. At what speed does he walk relative to the water? Thank you!
