1. The problem statement, all variables and given/known data You are starting a job for Montreal Police Colision Investigators. Your boss tells you to file a report on an accident on Notre-Dame Street. There has been an accident involving 2 cars. Your findings are as follows: Numerous debris were found at a distance of 12.25 m from the car The two cars stuck together and there are skid marks over 12.25 m There are also skid marks over a distance of 30 m before your debries The posted speed limit is 70 km/h Other data: m1=2,674 kg and m2=1,100kg From a friction block: Fv= 88.2N and Fh = 75.8N The second car was at rest Write a report for your superior on wether the car at fault should be charged with speeding (over 70 km/h) 2. Relevant equations μk = Fk/Fn 3. The attempt at a solution The coeficent of kinetic friction is 0.86 (μk = Fv/Fh) We have: Mass of both cars initial velocity of second car (0) final velocity of first car (0) distance of skid marks We need 2 know: Initial velocity of 1st car. How can we do this with only mass, distance of skid marks, and coeffiecent of friction?
