the professor knows that the speed of light, not love, is the only constant in the universe. The class boards a spaceship capable of travel at 0.8c.
a) If the ship was 150 m long when constructed, how long will it appear to the professor as they fly by at 0.8c?
b) the professor sets out in a backup ship to catch them. Relative to earth,
.9C the professor (S) moves at 0.9c toward the physics class (P) and away from the
earth while the class is also moving away from the earth at 0.8C, as shown at the right. What is the professors speed relative to the physics class?
0.9c 0.8c 10
