An inspection vehicle moves along a straight service tunnel. The table shows the total distance travelled at different times. The data would form a distance–time graph made of straight sections between consecutive readings.
| Time in s\mathrm{s}s | Distance in m\mathrm{m}m |
|---|---|
| 0 | 0 |
| 8 | 12 |
| 14 | 12 |
| 24 | 30 |
After 24 s, the vehicle continues for another 20 s at the same speed as during the final recorded section.
Calculate how much further the vehicle travels during these 20 s than it would travel in 20 s at its speed during the first section.
96 exam-style questions on Edexcel GCSE Physics 2.2 Speed, velocity and acceleration, covering 2.2.1 Speed and distance–time graphs, 2.2.2 Acceleration and the uniform-acceleration equation, 2.2.3 Velocity–time graphs, and 2.2.4 Measuring speed, typical speeds and free-fall acceleration. Each one has a worked solution and a mark scheme showing where the marks go.
