Directions: Answer the following questions in a scholarly manner.1. You saw a green light on a stoplight while driving at a constant high speed. At the samemoment, a policeman at rest saw the light as red. Using the concept of relativity, how are yougoing to defend yourself from a policeman who reprimanded you and gave you a ticket forspeeding?

The comment is written by professor. Please write your explain and reason detail. Also, please tell me where I'm wrong. 4. The special theory of relativity predicts that there is an upper limit to the speed of a particle. It therefore follows that there is also an upper limit on the following properties of a particle.a. the kinetic energyb. the total energyc. the linear momentumd. more than one of thesee. none of these
Hi, please show full solutions and also explain how you get the answers in physics term so it's understandable. The correct final answers are written beside too. This is one whole question to be answered. I can't post it separately since it's related. Thank you. 2. An astronaut in a spacecraft leaves Earth at a speed of 0.90c and travels 27 light-years away, both measured by an Earth-based observer. Hint: One light-year is the distance light travels in one year. a) How long will the journey take in years, as measured by the Earth-based observer? (30 years)b) How many years will have passed for the astronaut during the journey? (13 years)c) What distance will the astronaut measure the journey to be? (12 ly or 1.1 x 1017 m)
