When Barry enters the hallway, passing Clark, a spark jumps from Barry's elbow to the frame of the doorway he enters through. As Barry leaves the hallway, another spark jumps from his elbow to the frame of the doorway he leaves through. With this information ... A. How fast is Barry running in Clark's frame (in m/ns)? B. Find the time between the sparks measured by Clark, as expressed in meters? C. The space-time interval between the two sparks, as measured by Clark, as expressed in meters?

Clark Kent (a.k.a. Superman) is standing in the doorway of the entrance to a 525-meter-long hallway. (Lc = 525 m) Suddenly, Barry Allen (a.k.a. The Flash) runs down the length of the hallway at high speed (only 28% of the speed of light), as measured by Clark. (p or vc% = 28%) (Remember: c = 0.3 m/ns)

Expert Solution
Step 1

Given:

Length of the hall way, Lc = 525 m

Speed of flash measured by Clark, vc% = 28% of speed of light

Speed of light, c = 0.3 m/ns
