Ameter stick a hurtles through space at a speed v = 0.25c relative to you, with its length aligned with the direction of motion. you stand on earth and have another meter stick b with its length aligned with the direction of motion of meter stick a. you measure the length of meter stick a to be 1 m. what is the length of meter stick b, l_b, as seen in the rest frame of meter stick a?

Explanation:

Given:

Since the object is moving with a velocity comparable to the velocity of light  with respect to the observer therefore the length will appear shorter according to the theory of relativity.

Mathematical expression of the theory of relativity for length contraction:

where:

L = relativistic length

original length at rest

Lorentz factor

reserve is the answer

answer; how far out of place which the object finished relative to the starting location;
