Velma, who is moving past you at a high rate of speed, holds a meter stick and a standard kilogram
Is it possible that your measurements could show the standard kilogram to have a mass of 2 kg while the meter stick still has its normal length of 1 m? A) Yes, if Velma holds the meter stick parallel to its direction of motion. B) Yes, if Velma holds the meter stick perpendicular to its direction of motion. C) No, because mass actually decreases with velocity, rather than increasing. D) No; if the kilogram's mass has increased to 2 kg, then it must be longer than 1 m. E) No; if the kilogram's mass has increased to 2 kg, then it must be shorter than 1 m.
