A boat heads in the direction of 40° S of W at 13 m/s relative to the water across a river that flows to the north at 5.0m/s. (a) Draw vectors to represent the velocities of the boat relative to the water (ÜBw) and the water relative to shore (üws) on the diagram below. (N) (b) Write down the velocities of the boat relative to the water (BBw) and the water relative to shore (vws) in unit- vector notation.
