- 7. A meter stick is moving with speed 0.8c relative to a frame S .

(a) What is the stick’s length, as measured by observers in S , if the stick is parallel

to its velocity v ?

(b) What if the stick is perpendicular to v ?

(c) What if the stick is at 60 to v , as seen in the stick’s rest frame? [Hint: You can

imagine that the meter stick is the hypotenuse of a 30-60-90 right triangle]

(d) What if the stick is at 60 to v , as measured in S ?

I believe i have solved a-c , but cant figure out d, looking suggestions?
