The car of mass M shown has been “raked” by increasing the height of its center of mass to h This was done by raising the springs on the rear axle. If the coefficient of kinetic friction between the rear wheels and the ground is μ_k, show that the car can accelerate slightly faster than its counterpart for which h = 0. Neglect the mass of the wheels and driver and assume the front wheels at B are free to roll while the rear wheels slip.
