A coach is tested on a closed road. When travelling at 12 m/s, the coach has a braking distance of 12 m.
The same coach then travels at 18 m/s. The driver's reaction time is 0.70 s.
The mean braking force is the same in both tests. The driver sees a safety barrier 38 m ahead.
Use calculations to determine whether the coach stops before it reaches the safety barrier.
