39. Hannah tests her new sports car by racing with Sam, an AMT experienced racer. Both start from rest, but Hannah leaves the starting line 1.00 s after Sam does. Sam moves with a constant acceleration of 3.50 m/s², while Hannah maintains an acceleration of 4.90 m/s². Find (a) the time at which Hannah overtakes Sam, (b) the distance she travels before she catches him, and (c) the speeds of both cars at the T instant Hannah overtakes Sam.
