Please help!!!! this is all the question gives me and i cannot figure it out.
During an invasion by an alien empire, flying saucers (here labeled A and B) fly between two planets, as diagrammed on the right. The planets are at rest with respect to each other. The flying saucers' velocities are given with respect to the planets. The longer horizontal dimension of each saucer is referred to as its width. For each length or time interval listed below, indicate which observer(s) measure the proper time interval or proper length The time of saucer A's trip between planets The width of saucer B: The width of saucer A The distance between the planets:Explanation / Answer
While moving at relativistic speeds, time dilates for moving particles and length of moving particle contracts for other observers.
Proper time or length is the one measured by the moving particle itself.
so,
1. A reads its own time as proper time between planets.
2. B reads its own length as proper length.
3. A reads its own length as proper length.
4. P1 or P2 can measure distance between planets.
