Problem

A car skids on a horizontal road and its tyres slide without rolling. The coefficient of kinetic friction between the tyres and the road is

0.40

. If the speed of the car when skidding begins is

72\,\text{km}\,\text{h}^{-1}

, what is the minimum stopping distance? a)

102\,\text{m}

51\,\text{m}

25\,\text{m}

40\,\text{m}
