A fugitive tries to hop on a freight train traveling at a constant speed of 5.2 m/s . Just as an empty box car passes him, the fugitive starts from rest and accelerates at a = 1.2 m/s² to his maximum speed of 6.0 m/s . How long does it take him to catch up to the empty box car? Express your answer using two significant figures. ν ΑΣΦ ? t = Submit Request Answer Part B What is the distance traveled to reach the box car? Express your answer using two significant figures. ? d = m

Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.
