Special Relativity -- elapsed time while traveling at 0.95c

  1. Sep 1, 2016 #1
    1. The problem statement, all variables and given/known data
    A particle moving at 0.95c travels 10 m, as measured by a stationary observer, and then disappears. How long did the particle live (a) from the point of view of the observer and (b) from the point of view of the particle?

    2. Relevant equations
    t = d/v
    d = d0/gamma

    3. The attempt at a solution
    v = 0.95c, d0 = 10 m
    a) t0 = d0/v = 3.5E-8 s
    b) t = t0/gamma = 1.1*10-8 s

    Is this right?
