Tim kicks a ball off the ground. After t seconds, its height, h (in feet), is given by the formula h = -16t^2 + 64t. What is the maximum height reached by the ball?
\n" ); document.write( "------------------
\n" ); document.write( "You have a quadratic with a = -16 and b = 64
\n" ); document.write( "The max occurs when t = -b/2a = -64/(2*-16) = 2 second
\n" ); document.write( "---------------------
\n" ); document.write( "The height at t = 2 sec is as follows:
\n" ); document.write( "h(2) = -16(2)^2 + 64(2) = 64 ft
\n" ); document.write( "===========================
