A driver of a car travelling at
$52$
km
$h_{−1}$
applies the brakes and accelerates uniformly in the opposite direction. The car stops in
$5$
s. Another driver going at
$3$
km
$h_{−1}$
in another car applies his brakes slowly and stops in
$10$
s. On the same graph paper, plot the speed versus time graphs for the two cars. Which of the two cars travelled farther after the brakes were applied?
