A relativistic train with proper length 80 m passes through a tunnel with a proper length 65 m .
At this speed, how much time elapses for a cross-country trip of 5000 km, as measured on the train?
Alright Dude, If that worked for you... dont forget to give
THUMBS UP.(that will work for me!)
Please Vote...
If I missed something feel free to leave a comment.
atleast before giving downvote.
and, Thanks for using homeworklib- Smarter way to study.

A relativistic train of proper length 218 m approaches a tunnel of the same proper length, at a relative speed of 0.970c. A paint bomb in the engine room is set to explode (and cover everyone with blue paint) when the front of the train passes the far end of the tunnel (event FF). However, when the rear car passes the near end of the tunnel (event RN), a device in that car is set to send a signal to...

A supertrain of proper length 180 m travels at a speed of 0.86c as it passes through a tunnel having proper length 78.0 m. How much longer is the tunnel than the train or vice versa as seen by an observer at rest with respect to the tunnel?
A supertrain of proper length 205 m travels at a speed of 0.91c as it passes through a tunnel having proper length 86.0 m. How much longer is the tunnel than the train or vice versa as seen by an observer at rest with respect to the tunnel?
A supertrain of proper length 240 m travels at a speed of 0.89c as it passes through a tunnel having proper length 74.0 m. How much longer is the tunnel than the train or vice versa as seen by an observer at rest with respect to the tunnel?

An express train passes through a station that is 204 m long. It enters with an initial speed of 24 m/s and decelerates at a rate of 0.11 m/s2 as it goes through. a. During what time interval, is the front of the train within the station? b. How fast is the train moving when its front leaves the station? c. If the train is 134 m long, how long after the front of the train enters the station does...
Relativistic Length Measurements 4.7. Compute the contraction in length of a train 1/2 mile long when it is traveling at 100 mi/hr. Ans. 5.58 x 10-15 mi = 3.52 x 10-10 in. 4.8. At what speed must an observer move past the earth so that the earth appears like an ellipse whose major axis is six times its minor axis? Ans. 0.986c 49.

3. A satellite in Earth orbit passes through its perigee at a radius of rp 7000 km, and with speed p 9.4 km/s. Determine how much time elapses before the satellite returns to perigee.
Imagine that a relativistic train travels past your lecture room at a speed of 0.954 c. The passengers of the train claim that when they measure the length of the train using standard meter bars found on the train, the length comes out to be 73.6 m. What would be the length of the train in the frame of the lecture room if you measured it? (in m) A: 1.64 B: 2.37 C: 3.44 D: 4.99 E: 7.24 F: 1.05×101...
