Review Concept Simulation $9\mathrm{.}2$ and Conceptual Example $7$ as background material for this problem. A jet transport has a weight of $1\mathrm{.}09106$ N and is at rest on the runway. The two rear wheels are $16\mathrm{.}0$ m behind the front wheel, and the plane's center of gravity is $10\mathrm{.}8$ m behind the front wheel. Determine the normal force exerted by the ground on $($a$)$ the front wheel and on $($b$)$ each of the two rear wheels.
