Two motorcycle riders carry out emergency-stop tests on a dry test track.
| Rider | Speed in m/s\mathrm{m/s}m/s | Reaction time in s\mathrm{s}s | Braking distance in m\mathrm{m}m |
|---|---|---|---|
| M | 18 | 0.50 | 22 |
| N | 14 | 0.70 | 20 |
Which statement is correct?
M has the shorter thinking distance and the shorter stopping distance.
N has the shorter thinking distance but M has the shorter stopping distance.
M has the shorter thinking distance but N has the shorter stopping distance.
N has the shorter thinking distance and the shorter stopping distance.
126 exam-style questions on Edexcel GCSE Physics 2.5 Stopping and braking distances, covering 2.5.1 Stopping distance and reaction time, 2.5.2 Factors affecting stopping distance, 2.5.3 Dangers of large decelerations, and 2.5.4 Braking distance and initial speed. Each one has a worked solution and a mark scheme showing where the marks go.
