In a particular inertial reference frame, two events along the x-axis are observed/determined to occur 30 seconds apart temporally with the second event occurring after the first, and 34 light-seconds apart spatially with the spatial coordinate of the second being larger than the first.a)Above what minimum speed (as a fraction of c) would a second inertial observer need to travel along the first's positive x-axis so that the second event would be determined tooccur before the first? [Enter the exact speed, or 0 if you deem this to be not possible.]b)Suppose that an inertial observer travels exactly at the critical speed you found in part a), so that the events are deemed to be simultaneous (instead of in the opposite order). What is theexact spatial interval between the two events in this frame (with the same event 'labelling")? [If you concluded part a) was not possible, enter 0 here.]C. S

A spaceship leaves the solar system at v = (3/5)c and is headed towards a planet that is 20 c • years away (c is the speed of light).

Say that the clock on the ship began at zero. If this is the case, then what should the clock on the ship read when it arrives at the planet?

At relativistic speeds near that of light, the half-life of an unstable particle moving at high speed is longer than when it is at rest. an object is longer when moving than when it is stationary. O light emitted by a moving source moves at the same speed with the same frequency. effects precede causes in some inertial frames. lengths and times only appear different and have no effect on other measurable quantities.
Suppose a cosmic ray colliding with a nucleus in the Earth's upper atmosphere produces a muon that has speed v = 0.99c. The muon then travels at constant speed and lives 1.5 μs as measured in the muon's frame of reference.
