The proper mean lifetime of a subnuclear particle called a muon is 2 µs. muons in a beam are traveling at 0.902 c relative to a laboratory. the speed of light is 2.998 × 108 m/s. in the reference frame of the muon, how far does the laboratory travel in a typical lifetime of 2 µs?

To solve this problem it is necessary to apply the equations related to the time measured from a relative viewer and the mathematical equations of motion.

Speed is defined as

Where,

d = Distance

t = Time

Re-arrange to find d,

Applying the equations of relativity of time,

Where,

v = Velocity

c = speed of light

Reference time

t = relative time

Replacing,

Therefore the distance would be

Therefore the travel will be 5.5Km

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.

cant without the picture! ?
