Problem

A car passes point

A

on a straight highway and then moves with a constant acceleration of

-1.5\,\text{m/s}^2

for the next

10\,\text{s}

. At the end of this interval its speed is

5\,\text{m/s}

. (i) Determine the speed of the car as it passed point

A

. (ii) If the same acceleration continues beyond the

10\,\text{s}

, calculate the additional time required for the car to come to rest. (iii) Find the total change in velocity of the car from point

A

until it comes to rest.
