Classically when two objects move away from each other, the distance between them increases proportionally to the sum of their velocities. In special relativity, where velocities can get large, adding velocities can begin to pose problems. Consider the situation where an observer sees two spaceships flying apart with equal speeds V. Question 9 (1 point) How can the problem of the rockets going faster than the speed of light in their respective frames be rectified using special relativity? None of the above The relative velocity between the rockets is subject to relativistic velocity addition so it cannot be greater than C. The clocks aboard the rockets will appear to run more quickly relative to the observer so their velocities will appear slower to the observer. The length of the rockets is contracted relative to the observer so their velocities are less than C. Question 10 (1 point) If both rockets travel at speed 0.99c in the frame of the observer, what will be the observed velocity between one of the rockets in the rest frame of the other rocket? 0.99995c 0.99000c 0.99900c 0.99999c
