The automobile has a weight of 3300 lb and is traveling forward at 4 ft/s when it crashes into the wall. The impact occurs in 0.06 s. The figure shows a car crashing into a wall. If the coefficient of kinetic friction between the wheels and the pavement is μk = 0.3, calculate the impulsive force on the wall if the brakes were applied during the crash. The brakes are applied to all four wheels so that all the wheels slip
