Problem

An automobile of mass

1000\,\text{kg}

is travelling on a level road at

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

when the brakes are applied so that the wheels lock and slide. If the coefficient of kinetic friction between the tyres and the road is

0.60

, calculate the distance over which the car comes to rest. (Take

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