You measure the length of a passing Clingon spacecraft to be 155 m. If the Clingon spacecraft is moving at 0.58 the speed of light, what would be its length in metres if it was at rest relative to you? Give your answer to the nearest whole number.

A new unit of length is chosen such that the speed of light in vacuum is unity. What is the distance between the Sun and the Earth in terms of the new unit if light takes 8 min and 20 s to cover this distance?

4.Question 4The spaceships of Bob and Alice sit side-by-side at a spaceport. They measure them and both agree that each spaceship is 26 meters long. Alice takes off and Bob observes Alice's spaceship go by at a constant velocity such that the Lorentz factor is 2. Bob measures the length of his ship as Alice flies by. What value does he get?1 point52 meters13 meters26 meters

Justin is on a spaceship travelling at 0.998c. Onboard the ship is a table of length 2.5 m, with the length inline with the direction of travel of the ship. What is the length of the table as measured by Justin on the ship?

The length of a rocket is 100 m on the earth. When it was flying an observer on the earth measured its length as a 99m. Calculate the speed of the rocket. i. 3.78×107ms−13.78×107��−1 ii. 6.3×107ms−16.3×107��−1 iii. 7.8×107ms−17.8×107��−1 iv. 4.24×107ms−

A football has a diameter of 22cm. If the ball is travelling at a speed of 0.987c relative to the Earth, what is the length of it's smallest dimension as measured on the Earth? Use cm as the unit and give units.
