Question: A car, starting from rest, accelerates at the rate f through a distance s, then continues at a constant speed for time t and then

A car, starting from rest, accelerates at the rate f through a distance s, then continues at a constant speed for time t and then decelerates at the rate f/2 to come to rest. If the total distance traversed in 15 s, then

(a) s= ½ft²

(b) s= (¼)ft²

(d) s= (1/72)ft²
