Question

A spaceship passes you at a speed of 0.800 c. You measure its length to be 38.6 m Part A How long would it be when at rest? I

Answer 1

Answer #1

The formula for relativistic length is

L = L_o*(1 - (v/c)²)

putting all the values

38.6 = L_o*(1 - 0.8²)

L_o = 107.22 m

L_o is the rest length
