Here we apply concept of relative velocity in special relativity.

Imagine Punch lives on the Earth at rest. Judy is traveling past the earth with a speed of 0.600 c. If a rocket moving in the same direction passes Judy, Punch sees the speed of the rocket to be 0.930 c. What is the speed of the rocket seen by Judy in terms of the speed of the light?
Imagine a spaceship traveling at a constant speed through outer space. The length of the ship, as measured by a traveler aboard the ship, is 30.8 m. An observer on Earth, however, sees the ship as contracted by 19.7 cm along the direction of motion. What is the speed of the spaceship with respect to the Earth? (Express the speed as a fraction of c, the speed of light in a vacuum.) v c =
A spaceship is 1600 m long when it is at rest. When it is traveling at a certain constant speed its length is measured by external observers and it is found to be 1035 m. What is the speed of the spaceship in terms of the speed of light? Submit Answer Tries 0/12 In the kitchen of the spaceship the chef sets the oven timer for 1.75 hours to make roast beef. How much time does the roast beef spend...
A spaceship is moving past Earth at 0.99c. The spaceship fires two lasers. Laser A is in the same direction it is traveling, and Laser B is in the opposite direction. How fast will the light from each laser be traveling according to an observer on Earth? Select one: a. The light from Laser A will be traveling at 1.99c, the light from Laser B at 0.010 b. The light from Laser A will be traveling at c, the light...
Rocket A passes Earth at a speed of 0.76 c. At the same time, rocket B passes Earth moving 0.93 c relative to Earth in the same direction as A. Part A How fast is B moving relative to A when it passes A? Express your answer using two significant figures.
the spacecraft traveling at 0.99c continues on to space station positioned 1.5x10^9km from earth(according to earth measurements). how many hours, as measured on earth and as measured on the spaceship of food and air would the astronauts in the spacecraft need if the continue at a speed of 0.99c need to get there? 1. how far would the astronauts on the moving space ship think the distance from earth to the space station was? 2.suppose a light beam from earth...
A spaceship is 1600 m long when it is at rest. When it is traveling at a certain constant speed its length is measured by external observers and it is found to be 505 m. What is the speed of the spaceship in terms of the speed of light? 2.84*10^8 Hints: Objects moving at relativistic speeds shrink in the direction of motion. This is the so called Lorentz contraction. What is the relationship between the speed of the spaceship, its...
A spaceship leaves Earth traveling at 0.75 c. A second spaceship leaves the first at a speed of 0.87 c with respect to the first. Part A Calculate the speed of the second ship with respect to Earth if it is fired in the same direction the first spaceship is already moving. Take the positive direction in the direction of the first spaceship. Part B Calculate the speed of the second ship with respect to Earth if it is fired...
1. Which of these can be considered inertial reference frames? A: a car traveling on a straight road at a steady speed B: a car traveling on a straight road at increasing speed C: a car traveling around a curve at a steady speed both A and B both A and C both B and C A, B and C 2.A beam of light traveling to the right passes by an observer on...
