Problem
A river of width 200m flows uniformly from east to west with a speed of 3m s−1. A boat that can move at 6m s−1 in still water is aimed due north from the south bank.
(i) Calculate the magnitude and direction of the boat’s velocity with respect to the ground.
(ii) Determine the time taken by the boat to reach the opposite bank.
(iii) Find how far downstream from the point directly opposite to the starting point the boat finally lands.
