(10%) Problem 9: Slick Willy is in traffic court (again) contesting a $50.00 ticket for speeding. The speed limit was vo 50 mph and the police officer clocked Slick going vsw 68 mph. However, he was caught by a police officer driving towards him, so he is arguing that although the police officer measured him to be speeding, in reality he was not. Slick Willy is assuming that the Doppler shift in electromagnetic radiation is described in the same way...

Intro:
On July 25, 2010, a police officer was sitting in his police
cruiser adjacent to the 21st street bridge on U.S. 6, in Big
County, Ohio. The police officer was facing east watching traffic.
At around 3 AM, the police officer saw headlights approach at high
speed. He activated his radar and clocked the approaching suspect
car at 112 miles per hour. After the suspect car had passed the
officer's location, the officer turned left and proceeded to follow...

Question 8 (1 point Suppose that a police officer measured the speed of cars on a highway for an hour. The average speed of the cars was 70.5 and the standard deviation was 4.86. However, since the radar gun was biased, 4 is added to every observation in the dataset. What will the new mean be? 1) 74.5 2) 17.62 3) 4) 282 5) 70.5 Total enrollment in the Kalamazoo Public Schools have a mean and standard deviation of 11/485.2...

A radar gun used by a police officer measures your speed at a
certain instant in time, whereas an officer in a plane measures the
time it takes for you to travel the known distance between two
stripes painted on the highway.
What is the difference in nature between these two types of
measurement and which is the fairer basis for issuing a speeding
ticket?
Would your answer change if one stripe occurred before a rest
area and the other...

1.You are driving slowly on the highway at 50 mph when a police car with its lights flashing passes you going 100 mph. Relative to you, the police officer is moving 50 mph. Far in the future, when humans have mastered space travel, an astronaut is moving in a spaceship at half the speed of light, v = c/2, relative to earth, when a light beam sent from earth moving parallel to the spaceship passes it moving at v =...
