Question

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?

Answer 1

Answer: C

Explanation: 1m

Answer 2

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.
