Spaceship A is moving toward the Earth at 0.80c, and spaceship B is moving away from Earth at the same speed, according to observers on a distant planet. At the same moment, very bright lights are turned on at the front of spaceship A and on the back of spaceship B. The light from a)Spaceship A reaches the planet before the light from spaceship B. b)both ships reaches the planet at the same time. b)either ship could reach the planet first, but there's no way to tell in advance. d) Spaceship B reaches the planet before the light from spaceship A.
A spaceship departs from a space station and achieves a constant speed of 0.80cwith respect to thes tation, moving directly away from it. The spaceship fires a torpedo forward (in the same direction). The torpedo’s speed with respect to the spaceship is 0.40c. How fast is the torpedo moving with respect to the station?
Two students, Nora and Allison, are both the same age when Allison hops aboard a flying saucer and blasts off to achieve a cruising speed of 0.790c for a 17.5 year round trip (according to Allison). Neglecting the brief time periods required for the acceleration of the ship during blastoff and turnarounds, find the difference in age between Nora and Allison when they are reunited, difference in age: years Who is older? Allison They are still the same age. need more information Nora
In 2030, the Australian Space Agency launches a spaceship to our nearest neighbour Alpha Centauri, approximately 4 lightyears away. According to a clock on Earth how long will the rocket take to get there if it travels at v=0.999c=299482km/s (where 'c' is the speed of light equal to 299782km/s)? About 2 years. O About 6 years. O About 4 years. Zero time.
