You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 43.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 17.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 How fast (in miles per hour) was car A traveling just before the collision? (This problem uses English units because they would be used in a U.S. legal proceeding.)

You have been called to testify as an expert witness in a trial involving a head-on collision. Car A weighs 1515 lb and was traveling eastward. Car B weighs 1125 lb and was traveling westward at 44.0 mph. The cars locked bumpers and slid eastward with their wheels locked for 20.5 ft before stopping. You have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750. How fast (in miles per hour) was car A...
If you could please show the formulas used I would really appreciate it! 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 slop with brakes locked on all wheels. Measurements of the skid marks left by the tires showed them...
please explain.thank you You testify as an expert witness in a case involving an accident in which car A slid into the rear of car B, which was stopped at a red light along a road headed down a hill (see the figure). You find that the slope of the hill is θ = 11.0°, that the cars were separated by distance d = 20.0 m when the driver of car A put the car into a slide (it lacked...
You testify as an "expert witness" in a case involving an accident in which car A slid into the rear of car B, which was stopped at a red light along a road headed down a hill. You find that the slope of the hill is θ = 12.0°, that the cars were separated by distance d = 25.0 m when the driver of car A put the car into a slide (it lacked any automatic anti-brake-lock system), and that...
Name 37) You have been hired as an expert witness in a crash investigation. Car A of mass 1900 kg crashed into stationary car B of mass 1000 kg. You measure the coefficient of kinetic friction between the locked tires a was in park so the tires did not turn). Car A hits car B, locking bumpers so that they s bef nd the road to be 0.6 (car B kid off together. They skid 20 m ore coming to...
