A $10$ lb unbalanced wheel is rolling without slipping on a horizontal surface with an angular velocity of $1\mathrm{.}2$ rad$/$s clockwise and an angular acceleration of $9$ rad$/$s$2$ counter$-$clockwise. Given that the center of mass is $9$ in$.$ vertically above the center of the wheel, and that the radius of the wheel is $19$ in$.,$ determine the magnitude of the reactions of the ground on the wheel in lb$.$
