The table shows the speed of a cyclist at 4-second intervals:
| Time (sss) | Speed (m s−1\text{m}\ \text{s}^{-1}m s−1) |
|---|---|
| 0 | 2.0 |
| 4 | 5.0 |
| 8 | 7.0 |
| 12 | 8.5 |
| 16 | 9.5 |
Which row correctly describes the speed and the acceleration of the cyclist over this 16-second period?
Speed: decreasing; Acceleration: zero
Speed: decreasing; Acceleration: non-zero
Speed: increasing; Acceleration: zero
Speed: increasing; Acceleration: non-zero
