Two canoeists in identical canoes exert the same effort paddling and hence maintain the same speed relative to the water. One paddles directly upstream (and moves upstream),

whereas the other paddles directly down-stream. With downstream as the positive

direction, an observer on shore determines the velocities of the two canoes to be −1.3 m/s

and 2.9 m/s, respectively.

What is the speed of the water relative toshore? Answer in units of m/s.

What is the speed of the first canoe relativeto the water? Answer in units of m/s.

What is the speed of the second canoe relative to the water? Answer in units of m/s.
