you are a crime scene specialists. a car in an accident had skidded to a stop and left tire tracks for 32 meters. The coefficient of sliding friction between the tires and road is .45, and the car's mass is 1000kg. Was the driver exceeding 25mph (11.3m/s) speed limit?
u= Force Friction / Normal Force
F net= m*a
I can't figure it out because i dont think i know all the formulas i need to know.
