If the forklift's rear wheels supply a combined traction force of F_A = 300 lb, determine its acceleration and the normal reactions on the pairs of rear wheels and front wheels. The forklift has a weight of 2000 lb, with center of gravity at G₁, and the load weighs 900 lb, with center of gravity at G₂. The front wheels are free to roll. Neglect the weight of the wheels.
