- You have been hired as an expert witness in the future by an attorney representing the driver of a spacecraft. The driver is accused of exceeding the galactic speed limit of 0.700c relative to the Earth while being chased by a galactic police spacecraft. The driver claims he is innocent, that his speed was well below that limit. You have been provided with the following data: the police spacecraft was traveling at 0.600c while chasing the driver and a technician on the police spacecraft measured the suspected spacecraft as traveling at 0.300c relative to the police spacecraft. What advice should you give the attorney?arrow_forwardAnswer both of the following questions regarding Special Relativity: a) An astronaut leaves their twin behind on Earth and departs on a journey on a spacecraft travelling at a speed of 0.840c.

- It is year 2120 and we have figure out a propulsion system that allows spaceships travel at velocities as high as v = 0.87c. A first expedition to Alpha Centauri (the nearest planetary system) is being planned. Alpha Centauri is 4.3 ly away. Answer the following 5 questions below asking you about the details of this expedition. Question 10 Assuming a constant velocity of v=0.87c, how long would the trip to Alpha Centauri take as observed by the ground control team here on Earth? Give your answer in yearsarrow_forward6. One of the potentially confusing things about special relativity is that it shows us that the time measured between two events depends upon your inertial frame of reference. In particular, two events that appear to be simultaneous in one inertial frame may be measured to occur at different times in a different inertial frame. Even more interesting is that Event 1 might occur either before or after (or at the same time as) Event 2, depending upon your reference frame! The proper interpretation of these facts is to say that nothing in physics forces two simultaneous events in one frame to be simultaneous in any other frame. However, what about the order of events when Event 1 CAUSES Event 2? For example, let's consider two events from a game of pool: 1) A cue ball, traveling at 10 m/s, hits the eight ball (of mass equal to the cue ball). An elastic collision transfers all the linear momentum of the cue ball to the eight ball. 2) 0.1 seconds later, the eight ball sinks in a corner…arrow_forwardA particle traveling at 3.75 x 10^8 m/s is subjected to the special theory of relativity.
