Two boats are anchored in the harbor, separated by a horizontal distance of 18 m.
The boats bob up and down as waves enter the harbor. When one boat is at its
highest point, the other is at its lowest point and there are no wave crests between
them. Each boat makes exactly 5 complete up-and-down cycles every 10.0 s. The
vertical distance between a boat's highest and lowest position is 2.6 m.

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
