A driver approaches an intersection at a speed of 50km/h, when the light turns amber. The driver applies brakes to get the maximum stopping force without skidding. The car has a mass of 1500kg and the force of static friction between the tires and the road is 1.1*10^4N. Assuming the driver's reaction time is 0.3s. Find the maximum acceleration of the car, the maximum stopping time, and the minimum stopping distance.
