Physics
A rocket ship flies past the earth at 87.0 % of the speed of light. Inside, an astronaut who is undergoing a physical examination is having his height measured while he is lying down parallel to the direction the rocket ship is moving.
If his height is measured to be 1.96 m by his doctor inside the ship, what height would a person watching this from earth measure for his height?

0.967m
Explanation:
Rocket's speed = 0.87c
Where c is speed of light in space
Since he's lying vertical his height becomes a length
Lenght l' = Lenght in rocket = 1.96m
Percieved Lenght on earth l =?
Due to relativistic effect his length will be reduced to;
l = l'(1-(v/c)^2)^0.5
l = 1.96(1-0.87^2)^0.5
l = 1.96(1-0.7569)^0.5
l = 1.96(0.2431)^0.5
l = 1.96(0.4931) = 0.967m
