Question
Which of the following statements are IMPOSSIBLE? Choose all that apply.The rocket's speed was measured to be 1.98c.
The rocket's rest length is 283 m.
An observer flying by measured the rocket to be 68 m long.
A rocket flying away from the Sun at 0.87c measured the speed of the photons (particles of light) emitted by the Sun to be 0.58c.
An inertial reference frame had an acceleration of 18 m/s2. The proper time interval between two events was measured to be 272 s.
The time interval between the same two events (as measured by an observer not in the proper frame) was 231 s.
Explanation / Answer
The rocket's speed was measured to be 1.98c. --- Impossible, the speed of light 1c is the limit The rocket's rest length is 283 m. An observer flying by measured the rocket to be 68 m long. -- Possible due to lenght contraction at high speed. A rocket flying away from the Sun at 0.87c measured the speed of the photons (particles of light) emitted by the Sun to be 0.58c. --- Impossible, the speed of light, at which photons travel, is the same in any reference frame. They would measure 1c. An inertial reference frame had an acceleration of 18 m/s2. The proper time interval between two events was measured to be 272 s. --- Impossible, Inertial reference frame are non accelerating. The time interval between the same two events (as measured by an observer not in the proper frame) was 231 s.
