Meriam, Kraige & Bolton — Kinetics of Particles: Problem 3_283

3/283 A long fly ball strikes the wall at point $A$ (where $e_1 = 0.5$) and then hits the ground at $B$ (where $e_2 = 0.3$). The outfielder likes to catch the ball when it is 4 ft above the ground and 2 ft in front of him as shown. Determine the distance $x$ from the wall where he can catch the ball as described. Note the two possible solutions.
