Before takeoff, an astronaut measures the length of the spacecraft to be 37.24 m long using a steel rule. Once aboard the spacecraft with it traveling at 0.10c, he measures the length again using the same steel rule and finds a value of

(a) 37.05 m.
(b) 37.24 m.
(c) 37.43 m.
(d) Either 37.05 m or 37.24 m, depending on whether the ship's length is parallel or perpendicular to the direction of motion.
