Problem

A car starts from rest at a traffic signal and moves in a straight line with uniform acceleration until its speed becomes

72\,\text{km h}^{-1}

8\,\text{s}

. (i) Convert the final speed of the car into

\text{m s}^{-1}

. (ii) Calculate the magnitude of the uniform acceleration of the car. (iii) Determine the distance travelled by the car during these

8\,\text{s}
