The meter stick is now oriented vertically but still continues to move to the right at a velocity of 0.8 c. What length would you now measure the meter stick to be?
The relativistic contraction only affects the stick in the direction it's traveling. So if it's moving to the right but standing vertically, then I'll measure it to be 1 meter long, but the stick will be as skinny as a toothpick as it passes me.
