\n" ); document.write( "\n" ); document.write( "The function gives the height at time

. The ground is height zero. Set your function equal to zero and solve the quadratic for

. You will get one positive and one negative root. Since you don't care what happened BEFORE she hit the ball, discard the negative root.\r

\n" ); document.write( "\n" ); document.write( "And tell her to lay off those high ones. The given function models a ball hit when it was 4 feet off of the ground and given the low initial velocity, I'm figuring her for a middle schooler (12 to 13 years old) using a wooden bat against a pitcher of average skill. Hence 4 feet off the ground is somewhere up around her chin.\r
