An electric delivery van is travelling at 15 m s-1.
The driver sees a hazard in the road ahead and applies the brakes to bring the van to a stop.
The stopping distance of the van would be smaller if the van:
had a heavier cargo load
was travelling on a wet road
was travelling at a lower speed
had worn brake discs
