You are called as an expert witness to analyze the following auto accident: Car B, of mass 1900 kg. was stopped at a red light when it was hit from behind by car A, of mass 1500 kg. The cars locked bumpers during the collision and slid to a stop. Measurements of the skid marks left by the tires showed them to be 7.20 m long, and inspection of the tire tread revealed that the coefficient of kinetic friction between the tires and the road was 0.65. Part A What was the speed of car A just before the collision? Express your answer in kilometers per hour. km/h Submit Requost Answer Part B By how many km/h was car A exceeding the speed limit 60 km/h? Express your answer in kilometers per hour. ? Av = km/h Submit Request Answer You are called as an expert witness to analyze the following auto accident: Car B, of mass 1900 kg. was stopped at a red light when it was hit from behind by car A, of mass 1500 kg.
