The formula
Expresses the length, L, of a starship moving at velocity v with respect to an observer on Earth, where L0 is the length of the starship at rest and c is the speed of light.
Find
If a starship is traveling at velocities approaching the speed of light, what does the limit in part (a) indicate about its length from the perspective of a stationary viewer on Earth?
Explain why a left-hand limit is used in part(a).
