The Physics Journal Monday, February 9th,We started out class with a collection of a paper at the front desk. The paper named "I Wasn't Speeding! Activity: Physics 1"We are supposed to figure out the problem to the driving. A man man drives on 501 and screeches to a 20 foot stop before hitting a kid on a bike. The kid then falls off the bike after nearly being struck and bangs his head. A policewoman? comes to the scene and says by looking at the skid mark that the driver was speeding. We are supposed to figure out if the driver was speeding past the speed limit (45 mph). We are given: size of skid mark- 20 feet, speed limit- 45 mph, car has mass of 1200 kg, and 1 m/s=2.24 mph. We need to find all of the equations and such to answer the question. The scene is pictured above of the incident. To earn full credit we must address all aspects of the problem. All the equations and answers must be shown. We must portray the data in some kind of manner as if it were to a judge. A movie, poster, or rap would be a good solution. This paper is due the following Tuesday from tomorrow. It is worth 18 points and we may only work with 1 other person. The Energy transformations lab was also due today. The extra credit table that was assigned a week ago is also due today. It may be turned in anytime today, but will not be accepted after that. We continued to work on the lab the entire class period. If we did not finish the energy transformation lab, then we are supposed to finish that first. The work our way onto the I Wasn't Speeding Activity.Word Count: 299
