The graph above shows the relativity of time, space and mass [you must figure out which graph goes with which effect]. Suppose that Velma's spaceship is 100 m long and 10 m tall [from bottom to top] as measured by Velma. How long and how tall is her spaceship as measured by Mort, if she passes him at 90 % of lightspeed?
A) This question cannot be answered without knowing which observer is really at rest.
B) 100 m long and about 4.3 m tall
C) about 43 m long and 10 m tall
D) about 230 m long and 10 m tall
E) 100 m long and about 23 m tall

At 90% of the speed of light, length contraction occurs in the direction of motion. The length is contracted to about 43 m, while the height remains unchanged at 10 m.
