A spaceship,which has length 50 m and width 10 m when at rest,is moving in a direction along its length at a speed where its length contraction results in a 40-m length measured by a stationary observer.What would the measured width be in this case?
A)between 12 and 13 m
B)10 m
C)8 m
D)less than 8 m

Length contraction only affects the dimension parallel to the direction of motion. The width, being perpendicular to the direction of motion, remains unchanged at 10 m.
