An inspection vehicle moves through three straight sections of a tunnel. The table shows its motion in each section.
| section | speed in m/s | direction of travel |
|---|---|---|
| P | 5.0 | north |
| Q | 5.0 | east |
| R | 7.0 | east |
Compare the changes in speed and velocity as the vehicle moves from section P to section Q and then from section Q to section R.
