Race car A follows path a-a while race car B follows path b-b on the unbanked track. If each car has a constant speed limited to that corresponding to a lateral (normal) acceleration of 0.91g, determine the times tą and tg for both cars to negotiate the turn as delimited by the line C-C. 88 m/ 67 m a Answers: ta = ts = ----
