A girl throws a ball at an inclined wall from a height of $3 \mathrm{ft}$, hitting the wall at $A$ with a horizontal velocity $\mathbf{v}_{0}$ of magnitude $42.5 \mathrm{ft} / \mathrm{s}$. Knowing that the coefficient of restitution between the ball and the wall is 0.9 and neglecting friction, determine the distance $d$ from the foot of the wall to the Point $B$ where the ball will hit the ground after bouncing off the wall. The distance $d$ from the foot of the wall to the Point $B$ is $\mathrm{ft}$.
