duction: As a member of the accident reconstruction team for the local police department, you arrive on the scene pictured to the left. Upon starting your investigation, you learn that as the car was driving in the right lane, a bicyclist entered the road from the driver's right. The driver saw the bicycle entering his lane and applied the brakes hard in an attempt to avoid a collision. Unfortunately, the car was unable to stop and it collided into the bicycle.... Luckily no 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 are visible from the car going into the collision. They can be clearly seen leading up to the wheels of the car. Once you have measured the length of the skid marks, it is your job to determine the speed of the car before the skid begins. You have noted that the speed limit in the area is 35 mph. The officers who first responded have informed you that the bicyclist claims the driver was going well in excess of the speed limit. The driver, however, says that he was not speeding. Observations: Length of skid marks = 27.5 m Mass of car = 1200 kg Coefficient of friction (rubber on asphalt) = 0.67 Analvsis: 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 the skid. Assume that it was a level road 5. Where did the kinetic energy go? 6. Calculate the speed of the car before the brakes are applied. 7.Was the driver speeding? Explain
