An automobile accident occurs as follows: The driver of a full-size car (vehicle A, 4000 lb) is traveling on a dry, level road and approaches a stationary compact car (vehicle B, 2000 lb). Just 50 feet before collision, he applies the brakes, skidding all wheels. After impact, vehicle A skids an additional 50 ft and vehicle B, whose driver had all brakes fully applied, skids 100 ft. The final positions of the vehicles are shown in the figure. If the coefficient of kinetic friction is 0.90, was the driver of vehicle A exceeding the speed limit of 55 mi / hr before the initial application of his brakes?
