Which of the following statements are IMPOSSIBLE? Choose all that are. The rocket's speed was measured to be 1.72c. The rocket's rest length is 492 m. An observer flying by measured the rocket to be 966 m long. A rocket flying towards the Sun at 0.77c measured the speed of the photons (particles of light) emitted by the Sun to be c. An inertial reference frame had an acceleration of 18 m/s². The proper time interval between two events was measured to be 288 s. The time interval between the same two events (as measured by an observer not in the proper frame) was 316 s. X Part 2: True Statements Which of the following statements are TRUE? Choose all that are. The Lorentz factor, y, has a range that extends from zero to infinity. The range for the velocity of an object extends from 0 m/s to c. The elapsed time between two events (as seen in any frame) can never be greater than the proper time for those two events. An object's length (as seen in any IRF) can never be less than the object's rest length. The speed of a photon in a vacuum (as seen in ny IRF) has a rang that extends from 0 m/s to infinity.
