Problem

A motor-boat moves due north with a speed of 5 m s−15\,\text{m}\,\text{s}^{-1} relative to the river water. The river flows due east at 3 m s−13\,\text{m}\,\text{s}^{-1} relative to the ground. (i) Determine the velocity of the boat relative to the ground. (ii) Determine the velocity of the river water relative to the boat.
