Question 9

A tram driver sees a hazard on the track. The driver's reaction time is 0.80 s. From the moment the driver sees the hazard, the tram travels a total of 40 m before it stops. 30 m of this is travelled after the brakes are applied.

What was the speed of the tram when the driver saw the hazard?
