Step by step
Solved in 2 steps
- A rocket travels along a line from the Sun to Saturn at a constant speed of 0.862c relative to the Sun. The distance from the Sun to Saturn is 1.43 x 1012 m, as measured by someone at rest with respect to the Sun. How long does the journey take (in minutes) as measured by an astronaut on the rocket? (Use c = 2.9979 × 108 m/s) minThe 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 1 km spacecraft is racing towards the Sun at 0.75c. Using equations given in class, calculate the spacecraft length you measure from Earth. Treat Earth as not moving compared to the spacecraft's motion of 0.75 c.
- 1. An astronaut travels to a distant star with a speed of 0.46c relative to Earth. From the astronaut's point of view, the star is 4.40 ly from Earth. On the return trip, the astronaut travels with a speed of 0.90c relative to Earth. What is the distance covered on the return trip, as measured by the astronaut? Give your answer in ly f60 ss 0 ssf60* f60 ss 0 ssf6 ssf60 ssf6QHow far from the earth would you be able to travel in a lifetime of 88 years if you were able to travel at a constant speed of 0.67c?A spacecraft has a speed of 0.4c relative to Earth. As measured on Earth, the elapsed time between two events that happen at the same location on Earth is 4 h. Determine what the elapsed time between those two events would be from the spacecraft's frame.
- Two identical spaceships are under construction. The constructed length of each spaceship is 1.1 km. After being launched, spaceship A moves away from earth at a constant velocity (speed is 0.850c) with respect to the earth. Spaceship B follows in the same direction at a different constant velocity (speed is 0.6c) with respect to the earth. Determine the length that a passenger on one spaceship measures for the other spaceship.The star 61 Cygni A is 11.4 light-years from Earth. Imagine a spaceship that travels from Earth to 61 Cygni A at a constant speed of 0.921c. On Earth, we would measure the time it takes for the ship to reach the star to be 11.4 ly 0.921c = 12.4 years. (a) How much time (in years) would it take the ship to travel from the Earth to the star as measured by a traveler aboard the ship? years (b) What is the distance to the star (in light years) as measured by a traveler aboard the ship? lyInteractive LearningWare 28.10 reviews the concepts that play roles in this problem. The distance from earth to the center of our galaxy is about 30,000 ly (1 ly = 1 light year = 9.47 × 1015 m), as measured by an earth-based observer. A spaceship is to make this journey at a speed of 0.9990c. According to a clock on board the spaceship, how long will it take to make the trip? Express your answer in years. (1 yr is equal to 3.16 × 107 s.)
- An astronaut is traveling in a spacecraft at a speed of 0.8 times the speed of light (0.8c) relative to an observer on Earth. If the astronaut spends 5 years according to their own onboard clock, how much time will have passed on Earth when they return?Suppose a cosmic ray colliding with a nucleus in the Earth's upper atmosphere produces a muon that has a velocity v= 0.980c. The muon then travels at constant velocity and lives 1.52 us as measured in the muon's frame of reference. (You can imagine this as the muon's internal clock. See the figure below. Enter your answers to at least four significant figures. Assume the speed of light is 2.998 x 108 m/s.) اد us At (a) How long (in us) would the muon have lived as observed on the Earth if its velocity was 0.0690c? (b) How far (in m) would it have traveled as observed on the Earth? (c) What distance (in m) is this in the muon's frame?A star is located 42.8 lightyears from Earth. A spaceship travels to the star with a speed of 0.9870c. If an astronaut aboard the spaceship is 21 years old when the spaceship leaves Earth, how old is she when she reaches the star: a) According to an observer on Earth? b) According to her?
