At the start of a race, the rear drive wheels B of the 1550-lb car slip on the track. Determine the car’s acceleration and the normal reaction the track exerts on the front pair of wheels A and rear pair of wheels B. The coefficient of kinetic friction is μk = 0.7, and the mass center of the car is at G. The front wheels are free to roll. Neglect the mass of all the wheels.
