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 −1.2 m/s and + 2.9 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?

Solution Summary: The author explains how the speed of the water relative to the shore is 0.85m/s.

A car driving at 27m/s veers to the left to avoid a deer in the road. The maneuver takes 2.0s and the direction of travel is altered by 20 degrees. What is the average acceleration during the constant speed maneuver? Do this in accordance with the example in the chapter.
