2. C2 and C3 are cars parked by the side of the road. The speed limit of the road is 20 mph. C1 was driven by a negligent driver who was on an emotional rollercoaster due to his demanding girlfriend and was using his cell phone. The friction coefficients of the shoulder and pavement are 0.4 and 0.3 respectively. C1 saw C2 too late and hit the brakes. C1 skid 20 feet and hit C2. C2 skid 50 feet and hit C3. C3 skid on the shoulder 20 feet before it stopped. The driver of C3 was severely injured. His leg was broken and had his new car damaged severely. He sued C1 for negligence. In the court house C1 testified that he was travelling below the speed limit. C1, C2, and C3 have masses 4,3, and 2 kips respectively. You are hired by C3's attorney. Your job is to determine whether C1 broke the speed limit. If so, what was his speed at the time he hit the brakes. Your answer should be based on the principles and analysis of accident reconstruction engineering. 2. C2 and C3 are cars parked by the side of the road. The speed limit of the road is 20 mph.
