A minibus is tested with different numbers of passengers. All other conditions are unchanged.
| Test | Speed in m/s\mathrm{m/s}m/s | Thinking distance in m\mathrm{m}m | Stopping distance in m\mathrm{m}m |
|---|---|---|---|
| T | 12 | 6 | 22 |
| U | 12 | 6 | 28 |
Which change could explain the measurements in test U?
It carried more passengers, giving a greater mass and a longer thinking distance.
It carried more passengers, giving a greater mass and a longer braking distance.
It carried fewer passengers, giving a smaller mass and a longer braking distance.
It carried fewer passengers, giving a smaller mass and a longer thinking distance.
