Question : A car starting from rest, accelerates at the rate f through a distance S, then continues at constant speed for time t and then decelerates at the rate f/2 to come to rest. If the total distance travelled is 15S then

(a) S = ft

(b) S = (1/6) ft²

(d) None of the above

Answer : The right option is (d)

Solution :

A car starting from rest, accelerates at the rate f through a distance S
