6. A spaceship goes past a planet at a speed of 0.80 c. An observer on the planet measures the length of the moving spaceship as 40 m. He also says that his planet has a diameter of roughly 2.0 × 10⁰ m (a) How long does the woman on the spaceship measure the ship to be? (b) What does the woman on the spaceship measure the diameter of the planet to be? (c) If the rest mass of the spaceship is 3.0 x 105 kg, by how much would its mass increase when traveling at this speed? (d) According to the man on the planet, the spaceship takes 8.0 s to reach the next planet in his solar system. How long would the woman on the spaceship say it took?
