Observer A measures the velocity of a rocket as and a comet as .Here and are parallel and in the direction of the observer's positive x axis.The speed of the comet as measured by an observer on the rocket is: A)(u - v)/(1 - uv/c²) B)(u - v)/(1 - v²/c²) C)(u - v)/(1 - v²/c²)^1/2 D)(u - v)/(1 + uv/c²) E)(u + v)/(1 - uv/c²)

Question

Quizplus · Accepted Answer

The correct answer is A because the velocity of the comet as measured by an observer on the rocket is given by the formula (u - v)/(1 - uv/c^2), where u is the velocity of the rocket, v is the velocity of the comet, and c is the speed of light.
