\n" ); document.write( " Write a formula, s(t), that models the height of the baseball after t seconds.
\n" ); document.write( ":
\n" ); document.write( "s(t) = -16t^2 + 72t + 3
\n" ); document.write( "Where
\n" ); document.write( "s(t) = height after t seconds
\n" ); document.write( "-16t^2 = the downward pull of gravity
\n" ); document.write( "72t = initial upward velocity
\n" ); document.write( "3 = initial height of the bat
\n" ); document.write( ":
