Determine the maximum theoretical speed that may be achieved over a distance of 200 m by a car starting from rest, knowing that the coefficient of static friction is 0.80 between the tires and the pavement and that 65 percent of the weight of the car is distributed over its front wheels and 35 percent over its rear wheels. Assume (a) four-wheel drive, (b) front-wheel drive, (c) rear-wheel drive.
