Question Answered step-by-step Introduction: As a member of the accident reconstruction team for… Introduction:As a member of the accident reconstructionteam for the local police department, youarrive on the scene pictured to the left. Uponstarting your investigation, you learn that asthe car was driving in the right lane, a bicyclistentered the road from the driver’s right. Thedriver saw the bicycle entering his lane andapplied the brakes hard in an attempt to avoida collision. Unfortunately, the car was unableto stop and it collided into the bicycle…. Luckilyno one was injured seriously in the accident.At this time, the car is at a position of rest right after it struck the bicycle. Skid marks arevisible from the car going into the collision. They can be clearly seen leading up to the wheels ofthe car. Once you have measured the length of the skid marks, it is your job to determine thespeed of the car before the skid begins.You have noted that the speed limit in the area is 35 mph. The officers who firstresponded have informed you that the bicyclist claims the driver was going well in excess of thespeed limit. The driver, however, says that he was not speeding.Observations:Length of skid marks = 27.5 mMass of car = 1200 kgCoefficient of friction (rubber on asphalt) = 0.67Analvsis:1.Determine the weight of the car, and the Normal force (Fg and Fn)2. Calculate the magnitude of the force of friction the road applies to the car.3. Calculate the work done by friction to stop the car.4.Explain how the work you just calculated relates to the car’s kinetic energy before theskid. Assume that it was a level road5. Where did the kinetic energy go?6. Calculate the speed of the car before the brakes are applied.7.Was the driver speeding? Explain.
