A bicyclist is finishing his repair of a flat tire when a friend rides by with a constant speed of 3.5 m/s . Two seconds later the bicyclist hops on his bike and accelerates at 2.4m/s2 until he catches his friend. How much timedoes it take until he catches his friend (after his friend passeshim)? What is his speed when he catches up? How far has he traveled in this time?
