The car accelerates uniformly from rest to speed v in time t. If it has weight W and a center of gravity at G, determine the normal reaction of each wheel on the pavement during the motion. Power is developed at the front wheels, whereas the rear wheels are free to roll. Neglect the mass of the wheels and take the coefficients of static and kinetic friction to be μ_s and μ_k respectively.
