Problem

A car starts from rest, accelerates uniformly at

2\,\text{m}\,\text{s}^{-2}

for

5\,\text{s}

and then continues with the speed thus attained for the next

10\,\text{s}

. What is the total displacement of the car in this

15\,\text{s}

interval? a)

150\,\text{m}

75\,\text{m}

125\,\text{m}

100\,\text{m}
