Use a(t) = -9.8 meters per second per second as the acceleration due to gravity. (Neglect air resistance.)
\n" ); document.write( "A baseball is thrown upward from a height of 3 meters with an initial velocity of 11 meters per second. Determine its maximum height. (Round your answer to two decimal places.)
\n" ); document.write( ":
\n" ); document.write( "The equation for this
\n" ); document.write( "h(x) = -9.8x^2 + 11x + 3
\n" ); document.write( ":
\n" ); document.write( "Find the axis of symmetry: x = -b/(2a)
\n" ); document.write( "x = \"%28-11%29%2F%282%2A-9.8%29\"
\n" ); document.write( "x = \"%28-11%29%2F%28-19.6%29\"
\n" ); document.write( "x = +.561 secs is when max height occurs
\n" ); document.write( ":
\n" ); document.write( "Find the height, replace x with .561
\n" ); document.write( "h(x) = -9.8(.561^2) + 11(.561) + 3
\n" ); document.write( "h(x) = -9.8(.315) + 6.171 + 3
\n" ); document.write( "h(x) = -3.084 + 6.171 + 3
\n" ); document.write( "h(x) = 6.087 meters is max height
\n" ); document.write( "
\n" );
