John travels until he reaches the 147 km marker and then retraces his path to the 172 km marker. What is John’s resultant displacement ±rom the 234 km marker? Answer in units o± km Your answer must be within ± 1.0% 002 (part 2 of 2) 10.0 points How ±ar has he traveled? Answer in units o± km Your answer must be within ± 1.0% 003 (part 1 of 2) 10.0 points A bug completes one lap along the edge o± a circular planter o± radius 21 . 6 cm in 9 . 296 s. How ±ast was it traveling? Answer in units o± cm / s Your answer must be within ± 1.0% 004 (part 2 of 2) 10.0 points How ±ast in m/s? Answer in units o± m / s Your answer must be within ± 1.0% 005 (part 1 of 2) 10.0 points A runner is jogging at a steady 7 . 8 km / hr. When the runner is 5 . 6 km ±rom the Fnish line, a bird begins ²ying ±rom the runner to the Fnish line at 23 . 4 km / hr (3 times as ±ast as the runner). When the bird reaches the Fnish line, it turns around and ²ies back to the runner. L v b v r finish line How ±ar does the bird travel? Even though the bird is a dodo, assume that it occupies only one point in space (a “zero” length bird) and that it can turn without loss o± speed. Answer in units o± km Your answer must be within ± 1.0% 006 (part 2 of 2) 10.0 points A±ter this Frst encounter, the bird then turns around and ²ies ±rom the runner back to the Fnish line, turns around again and ²ies back to the runner. The bird repeats the back and ±orth trips until the runner reaches the Fnish line. How ±ar does the bird travel ±rom the be- ginning (including the distance traveled to the Frst encounter)?
