Two cars, A and B, travel in a straight line. The distance of A from the starting point is given as a function of time by >At) = at + pt, with a = 2.60 m/s and p = 1.20 m/s. The distance of B from the starting point is XB (t) = Yt2 - /) t, with 'Y = 2.80rm/s and/) = 0.20rn}s.
(a)Which car is a bead just after they leave the starting point?
(b) At what time(s) are the cars at the same point?
(c) At what time(s) is the distance from A to B neither increasing nor decreasing?
(d) At what time(s) do A and B have the same acce1eratinn?
