A meter stick having a rest mass of 1 kg moves past you. Your measurements show it to have a mass of 2 kg and a length of 1 m. How is the stick oriented, as observed by you?
 
  A) perpendicular to its direction of motion
  B) parallel to its direction of motion
  C) It is impossible to say anything about the orientation without further information.
  D) Nonsense--if the stick's mass has increased to 2 kg, then it must be longer than 1 m.

  What will be an ideal response?
