Two cars start a race at rest. Car A accelerates at constant rate a, while car J
moves with constant jerk j and zero initial acceleration. Part way through the race,
at t = 1 s, the cars are tied.
(b) In a single graph, sketch x(t) for both Car A and Car J, and label
the curves accordingly.
(c) Who was ahead at t = 0.5 s?
(d) Which car will win the race?
