Question

A driver of a car travelling at 52 km h- applies the brakes and
accelerates uniformly in the opposite direction. The car stops
in 5 s. Another driver going at 3 km h- 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?​​

Answer 1

v=u+at

0=52+a(5)

a=-52/5

s=ut+1/2 at²

s=52(5)+1/2(-52/5)(5)²

2nd case:

0=3+a(10)

a=-10/3

s=3(10)+1/2(-3/10)(100)

Pls calculate "s" and compare it. sorry
