![A policeman pulls over a motorist for running a red light. The motorist explains that the light was not red but green and has a photo to prove it. Remembering his physics, the policemen then arrests the motorist for gross speeding and hauls him off to jail. If the speed limit was 80 km/h how many times over the speed limit was the motorist traveling?

A physicist is arrested for running a red light. In court, he pleads that he approached the intersection at such a speed that the light looked green to him. The judge, having taken a couple physics courses as an undergraduate, changes the charge to speeding and fines the defendant S1 for every mile per hour over the local speed limit of 30 miles per hour. What is the fine? Assume the wavelength of green light is 530 nm and the...
A motorist is traveling at 54 km/h when she observes that a traffic light 240 m ahead of her turns red. The traffic light is timed to stay red for 24 s.
A motorist is traveling at 54
km/h when she observes that a traffic light 240 m ahead of her
turns red. The traffic light is timed to stay red for 24 s. If the
motorist wishes to pass the light without stopping just as it turns
green again, determine (a) the required uniform deceleration of the
car, (b) the speed of the car as it passes the light.

A driver disregards a red light (Λ = 750 nm) at an intersection and decides to run it. They are caught by a police officer and are given a ticket. When they arrive in court, they decide to say that they were traveling so fast that the red light appeared green (Λ = 450 nm). After careful thought, the judge presented the individual with two choices: either pay the actual amount on the ticket or pay $1 for every mile...

You're caught running a red light on Hwy 316. Attempting to impress the skeptical patrol officer with your physics knowledge, you claim that you were traveling so fast that the red light (746 nm) appeared yellow (581 nm) to you. How fast would you have been traveling (in mi/hr) if that had been the case?

3) Suppose you are pulled over for running a red light. You try to trick the officer who pulled you over and say that due to the Doppler shift, you didn't even see a light. However, the officer knows physics and decides to give you a ticket based on the speed needed to shift red light to ultraviolet light if the light was stationary. The officer decides to give a ticket which is $10 for every mile per hour you...
