Homework Help: Physics

Posted by Anonymous on Sunday, February 19, 2012 at 11:47pm.

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 downstream. With downstream as the positive direction, an observer on shore determines the velocities of the two canoes to be
−1.7 m/s
and +2.5 m/s, respectively.
(a) What is the speed of the water relative to the shore?

(b) What is the speed of each canoe relative to the water?
