B.What is the orientation angle in a reference frame moving with the rod?

Please help I know length contraction formula is involved but I keep getting an incorrect answer of 2.95 m. I have no idea on part B

**Count Iblis**, Wednesday, April 14, 2010 at 5:28pmLx' = 1/gamma Lx

Ly' = Ly

It is given that

Lx' = 1/2 sqrt(3) * 2 m = sqrt(3) m

This means that

Lx = gamma sqrt(3) m = 2.95 m

Ly' = 1/2 * 2 m = 1 m

So, we have:

Ly = Ly' = 1 m

The proper length is thus:

L = sqrt(Lx^2 + Ly^2) = 3.12 m
