a wagon passes above us in a spaceship with a length of 87 m at a speed of 1 500,000 m/s
how far is the spaceship observed from earth at the same speed as it is experienced by the wagons on the ship
Step by step
Solved in 2 steps
- A spaceship leaves Earth on a one-way star trip that earthbound observers judge will take 25 years. If the ship travels at 0.95c rela- tive to Earth, how long will the trip take as judged by observers in the ship?Give some examples of what we currently use holograms for, and one or two examples of what we might see in the future.At what speed will a 1 m rule be moving if it its apparent length is measured by a stationary observer to be 0.5 m?
- A way to measure the length of an object moving at known(relativistic) speed is to measure the interval between the passage of referencepoints past an observer. By considering the times at which the leading and trailling ends of a moving rod pass an observer, and applying Lorentz transformations,show that the same expression for length contraction as : L=yo-1L' is obtained,draw a spacetime diagram if neededY6If two spaceships are heading directly toward each other at 0.800c, at what speed must a canister be shot from the first ship to approach the other at 0.999c as seen by the second ship?
