a baseball player hits a fly ball that is caught about 5 seconds later by an outfielder. the path of the ball is a parabola. the ball is at its highest point as it passes the second baseman, who is 117 feet from home plate. about how far from home plate is the out fielder at the moment he catches the ball? explain your reasoning.
The highest point, the vertex is halfway out because the parabola is symmetric about vertical line through the vertex.
so at 117*2 = 234.
