Problem

A car of mass

1000\,\text{kg}

is moving on a horizontal road at

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

. The driver applies the brakes producing a constant retarding force of

5000\,\text{N}

. Neglecting all other forces, find the distance the car travels before coming to rest. a)

80\,\text{m}

40\,\text{m}

20\,\text{m}

32\,\text{m}
