Workers have loaded a delivery truck in such a way that its center of gravity is only slightly forward of the rear axle, as shown in the drawing. The mass of the truck and its contents is 8340 kg. Find the magnitudes of the forces exerted by the ground on the following.
a) the front wheels (in N)
b)the rear wheels of the truck (in N)

Use the law of moments to answer this question.
The total of the rear wheel forces and the front wheel forces equals the weight, M g = 81,732 N.
Most of the weight will be on the rear wheels.
You will need to know the distance of the center of gravity from the rear wheels, and the distance between front and back wheels.
These numbers should be on the drawing that you have not provided.
