The table shows the readings on a bicycle computer measuring speed at 3 s intervals as a cyclist climbs a hill.
| Time (s\text{s}s) | Speed (m s−1\text{m s}^{-1}m s−1) |
|---|---|
| 0 | 12.0 |
| 3 | 9.0 |
| 6 | 7.0 |
| 9 | 5.5 |
| 12 | 4.5 |
Which option correctly describes the speed and the acceleration of the cyclist?
Speed is increasing; acceleration is zero
Speed is increasing; acceleration is not zero
Speed is decreasing; acceleration is zero
Speed is decreasing; acceleration is not zero
