An automobile starts from rest at a traffic signal and moves along a straight road with a constant acceleration for the next 8s, after which it continues at the speed attained.
(i) If the car covers 160m in the first 8s, calculate its acceleration.
(ii) Determine the speed of the car at the instant the acceleration phase ends.
(iii) How much additional distance will the car cover in the next 20s of uniform motion at this speed?
