PHY2061 R. D. Field Problems Relativity Page 1 of 3 Relativity Problems Problem 1: A rod whose length at rest is 10 meters is moving to the right along the positive x-axis of the O-frame with velocity V = 0.8c . An observer riding on the rod ( i.e. in the O'-frame ) sets off two explosions simultaneously – so he says. If the rod is parallel to the x-axis how far apart are the two explosions ( in meters ) in the O-frame ? Is this length the same as the length of the rod as measured in the O-frame ? If your answer is no, then what is the length of the rod ( in meters ) as measured in the O-frame ? Problem 2: In the previous problem, what is the time interval between the two explosions ( in seconds ) as measured in the O-frame ? Which explosion occurred first in the O-frame , the one at the left or right end of the rod? Problem 3: A planet called Zilch is located 2 light-years away from Earth (as measured in a frame at rest with respect to the Earth). At the instant a rocket heading for Earth passes planet Zilch a baby (named Sally) is born on the rocket. (a)
