A car travels at 60 km / h on a straight road. The road is dry. The driver applies the brakes suddenly. The table shows the thinking distance, the braking distance and the stopping distance. thinking distance / m | braking distance / m | stopping distance / m 27 | 22 | 49 The same car is driven by the same driver at 60 km / h on the same road when it is wet. The driver applies the brakes suddenly again. What is the effect of the wet road on the thinking distance, the braking distance and the stopping distance?
