Observer a Measures the Velocity of a Rocket as

Question 9

Multiple Choice

Observer A measures the velocity of a rocket as Observer A measures the velocity of a rocket as and a comet as . Here 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/c<sup>2</sup>) B) (u - v) /(1 - v<sup>2</sup>/c<sup>2</sup>) C) (u - v) /(1 - v<sup>2</sup>/c<sup>2</sup>) <sup>1/2</sup> D) (u - v) /(1 + uv/c<sup>2</sup>) E) (u + v) /(1 - uv/c<sup>2</sup>) and a comet as Observer A measures the velocity of a rocket as and a comet as . Here 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/c<sup>2</sup>) B) (u - v) /(1 - v<sup>2</sup>/c<sup>2</sup>) C) (u - v) /(1 - v<sup>2</sup>/c<sup>2</sup>) <sup>1/2</sup> D) (u - v) /(1 + uv/c<sup>2</sup>) E) (u + v) /(1 - uv/c<sup>2</sup>) . Here Observer A measures the velocity of a rocket as and a comet as . Here 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/c<sup>2</sup>) B) (u - v) /(1 - v<sup>2</sup>/c<sup>2</sup>) C) (u - v) /(1 - v<sup>2</sup>/c<sup>2</sup>) <sup>1/2</sup> D) (u - v) /(1 + uv/c<sup>2</sup>) E) (u + v) /(1 - uv/c<sup>2</sup>) 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)
