A canoe travels across a 40-m-wide river that has a current of speed 5.0 m/s. The canoe has a speed of 0.80 m/s relative to the water (Fig. P4.88). The person paddles the canoe so as to cross the river as fast as possible. (a) What is the canoe’s velocity relative to an observer on shore? Give the magnitude and direction of the velocity vector. (b) How far downstream does the canoe travel as it crosses from one side of the river to the other?
