Please refer to the link below for the problem statement and known data. http://imgur.com/1CQPk Calculate the velocity of the muons as they leave the accelerator. From my understanding, I must manipulate the Time Dilation equation in such a way so as to make velocity 'v' the subject of the equation. So far I haven't been able to manipulate and can't think of any other methods I can use to find the muons velocity. (Im assuming its value is close the the speed of light Please note, Unfortunately I do not have answers, just marking guidelines which don't help me at all. Any help will be appreciated.
