A fugitive tries to hop on a freight train traveling at a constant speed of 5.0 m/s. Just as an empty box car passes him, the fugitive starts from rest and accelerates at a = 3.5 m/s2 to his maximum speed of 8 m/s.
(a) How long does it take him to catch up to the empty box car?
(b) What is the distance traveled to reach the box car?
