A spaceship,which has length 35 m and width 16 m when at rest,is moving in a direction along its length at a speed where its length contraction results in a 28-m length measured by a stationary observer.What would the measured width be in this case?
A)between 18 and 20 m
B)16 m
C)13 m
D)less than 13 m
E)20 m

Length contraction only affects the dimensions of an object in the direction of its motion. Since the width of the spaceship is perpendicular to its direction of motion, it remains unchanged at 16 m, as observed by a stationary observer.
