Problem

A car of mass

1000\,\text{kg}

is travelling at

20\,\text{m}\,\text{s}^{-1}

on a horizontal road. The brakes are applied and the car skids to a halt. If the coefficient of kinetic friction between tyres and road is

0.40

(take

g = 9.8\,\text{m}\,\text{s}^{-2}

), the stopping distance of the car is closest to (a)

81\,\text{m}

(b)

50\,\text{m}

(c)

51\,\text{m}

(d)

102\,\text{m}
