Chapter 14.1, Problem 14.21P

An expert archer demonstrates his ability by hitting tennis balls thrown by an assistant. A 2-oz tennis ball has a velocity of $\left(32\text{ft/s}\right)i-\left(7\text{ft/s}\right)j$ and is 33 ft above the ground when it is hit by a 1.2-oz arrow traveling with a velocity of $\left(165\text{ft/s}\right)\text{j}+\left(230\text{ft/s}\right)\text{k}$ , where j is directed upward. Determine the position P where the ball and arrow will hit the ground, relative to point O located directly under the point of impact.
