Two cars A & B travel in a straight line from same point. The distance of A from the starting point is given by xA = α t + β t2 where α = 2.6 m/s and β = 1.2 m/s2. The distance B from the starting point is xB = γ t2 – δ t3; where γ = 2.8 m/s2 and δ = 0.2 m/s3.
(i) Which car is ahead just after they leave the starting point?
