Homework Equations
tpγ=t
Lp/γ=L
The Attempt at a Solution
The problem is under the category of length contraction and time dilation so I assume these are the two equations I must use. However when trying to do the problem I only was given t and Lp, and yet there are three variables (tp, L, and v). Help ;-(
