γ = 1 / sqrt(1 - (0.6c)^2/c^2) = 1 / sqrt(1 - 0.36) = 1 / sqrt(0.64) = 1 / 0.8 = 1.25
Using the Lorentz factor calculated earlier, we can plug in the values: Arthur Beiser Modern Physics Solutions Of Chapter 2 Pdf
This means that the observer will measure the length of the object to be 0.436 times its proper length. γ = 1 / sqrt(1 - (0
