- A spacecraft is moving at speed 0.61c relative to two star systems—star system A and star system B— that are always the same distance apart with respect to each other. Observers aboard the spacecraft measure the time taken to travel from start system A to star system B as 23.22 years. What is the distance between the two star systems, in light-years, as measured by an observer that is bound to star system B.2. A ladder 6.00 m long leans against a wall inside a spaceship. From the point of view of a person on the ship, the base of the ladder is 2.10 m from the wall, and the top of the ladder is 5.62 m above the floor. The spaceship moves past the Earth with a speed of 0.86c in a direction parallel to the floor of the ship. Find the angle the ladder makes with the floor, as seen by an observer on Earth. 239119 16 ociA spaceship travels at 0.818c relative to Earth. If the spaceship fires a small rocket in the forward direction, how fast (relative to the ship) must it be fired for it to travel at 0.870c relative to Earth?
- A spacecraft travels along a space station platform at 0.65c relative to the platform. An astronaut on the spacecraft determines the platform to be 3.00 X 102m long. What is the length of the platform as measured by an observer on the platform?You are driving down a two-lane country road, and a truck in the opposite lane is traveling toward you. Suppose that the speed of light in a vacuum is c = 69 m/s. Determine the speed of the truck relative to you when (a) your speed is 25 m/s and the truck’s speed is 35 m/s and (b) your speed is 5.0 m/s and the truck’s speed is 55 m/s. The speeds given in parts (a) and (b) are relative to the ground.An alien spaceship traveling 0.600c toward Earth launches a landing craft with an advance guard of purchasing agents. The lander travels in the same direction with a velocity 0.800c relative to the spaceship. As observed on Earth, the spaceship is 0.200 light-years from Earth when the lander is launched. (a) With what velocity is the lander observed to be approaching by observers on Earth? (b) What is the distance to Earth at the time of lander launch, as observed by the aliens on the mother ship? (c) How long does it take the lander to reach Earth as observed by the aliens on the mother ship? (d) If the lander has a mass of 4.00 × 105 kg, what is its kinetic energy as observed in Earth’s reference frame?
- The Starship Enterprise, according some Trekkie analysts, is 300 meters long. If it is traveling at 0.985c. what would be the value of L, its length as seen from Earth?A duck, standing by the side of the road at night, sees a car approaching at a speed of 0.2c. If the driver is shining a flashlight forward as the car advances, find the speed of the light from the flashlight relative to the duck.The nearest star to Earth is Proxima Centauri, which is 4.3 light years away. The spacecraft Potemkin is sent to this star at a constant velocity of 0.73c, and the craft carries a light beacon that flashes once a day to signal the earth that all is well. While traveling to the star the Potemkin passes a similar ship returning from the star at the same speed. How long does the trip take according to the space travelers inside the Potemkin? (b) (a) How long does the trip take according to Earth observers? (c) According to the space travelers inside the Potemkin, what is the distance to Proxima Centauri? (d) What is the speed of the returning craft as seen from the Potemkin What is the rate at which flashes are seen on Earth from the Potemkin? (e) (f) What is the rate of flashes sent by the returning craft as seen by the Earth observers?
- 2. A ladder 5.50 m long leans against a wall inside a spaceship. From the point of view of a person on the ship, the top of the ladder is 4.79 m above the floor. The spaceship moves past the Earth with a speed of 0.95c in a direction parallel to the floor of the ship. What is the length of the ladder as seen by an observer on Earth? mSomeone in Earth's rest frame says that a spaceship's trip between two planets took 10.0 years, while an astronaut on the space ship says that the trip took 6.27 years. Find the speed of the spaceship (as measured by someone in Earth's rest frame) in terms of the speed of light. 0.959c 0.687c 0.489c 0.684c 0.779cA rocket launched outward from Earth has a speed of 0.38c relative to the Earth.
