8.Question 8If you are traveling in a spaceship that passes by Earth at a velocity of 0.8c, and you fire an escape pod from your spaceship (pointed in your direction of travel) that has a speed of 0.7c with respect to your ship, what is the speed of the escape pod from the perspective of a person on Earth? (Note: You don’t need a calculator to answer this question--think about the possible answers listed.)1 point0.7c0.8c1.5cNone of the above

10.Question 10Imagine that you are traveling in a spaceship that passes by Earth at a velocity of 0.87c (Lorentz factor = 2), and you fire an escape pod from your spaceship pointed straight up (in the y or z direction, perpendicular to the spaceship’s direction of travel). If the escape pod has a perpendicular speed of 0.6c with respect to your ship, what is the perpendicular speed of the escape pod from the perspective of a person on Earth?

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−

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?

A body is projected from the earth's surface with the intention of letting it escape from the earth's gravitational field. What is the minimum escape velocity of the body? [Earth's radius = 6.4 x 103km, g = 10ms-2]

A space vehicle is traveling at 4500 km/h relative to the Earth when the exhausted rocket motor is disengaged and sent backward with a speed of 70 km/h relative to the command module. The mass of the motor is four times the mass of the module. What is the speed of the command module relative to Earth after the separation? km/h
