Question
5. Two motorcycles are at rest and separated by 24.5 ft. They
start at the same time in the same direction, the one in the
back having an acceleration of 3 ft. per sec2, the one in the
front going slower at an acceleration of 2 ft. per sec2.
(a) How long does it take for the faster cycle to overtake the
slower?
(b)How far does the faster machine go before it catches up?
(c) How fast is each cycle going at this time?
