# 2 observer diagram, relativity

1. The problem statement, all variables and given/known data
A futuristic flying car, 100m long in the horizontal x direction, lifts off vertically from the ground at 0.1c. A plane flies past at 0.65c in the positive x direction. According to the ground observer the car remains parallel with the horizontal x axis.

a. draw a 2 observer diagram, to show that the car appears tilted with respect to the x' axis measured by the observer on the plane.

b.calculate the tilt angle measured by the observer in the plane.

3. The attempt at a solution
unsure with a.
went straight to b.
let the left end of the car x=y=x'=y'=t=t'=0..
then we are told somehow to calculate the right end the car remembering that y'=uy't'?????

please can someone put some sense into this question, because im very very confused, on how to do either a or b.
