Hello.
I am doing a special relativity question.
I got a particle traveling at some speed v. It travels 20000 light years from reference of galaxy in 30 years from the reference of the particle.
I need to find the speed of the particle.
Well, i tried to use time dilation and length contraction formulas but i end up with 3 unknown and 2 equations.
So after thinking a little more i made up another equation:
30 years=Dialated length/velocity.
Of course the units were correct years into seconds and so on.
Then i bassicle get 2 v's, one inside the gamme and the other one on the bottom of the fraction, but the answer i get is C. So i made a mistake somewhere...any ideas?
Thx
