When the runner is L= 5.5 km from the finish line, a bird begins flying straight from the runner to the finish line at v 20.4 km/hr (3 times as fast as the runner). When the bird reaches the finish line, it turns around and flies directly back to the runner. Ub finish line L What cumulative distance does the bird travel? Even though the bird is a dodo, as- sume that it occupies only one point in space (a "zero" length bird), travels in a straight line, and that it can turn without loss of speed.
