A car is approach a corner too fast and locks up the brakes at point A and holds them on for 12.5 M to point B. The car then moves from point B at a constant speed and does into the corner. At Point C because the car is still going to fast it goes out of control and leave the road the mass of the care is 850 kg. The radius of the corner is 20.0m. The force of friction between the tires and the road is 38250N in the corner as well as between points A and B. Calculate the minimum speed that the car must have had at point A.
