The height h, in feet, of a baseball above the ground t seconds after it is hit is given by h = -16^2 + 52t + 4.5. Use this equation to determine the number of seconds, to the nearest 0.1 second, from the time the ball is hit until the ball hits the ground.
\n" ); document.write( "APART FROM START WHEN H=0 AT T=0.
\n" ); document.write( "WHEN IT HITS THE GROUND AGAIN H=0
\n" ); document.write( "SO WE HAVE TO FIND T FOR THIS CASE
\n" ); document.write( "16T^2-52T-4.5=0
\n" ); document.write( "T=[52+SQRT{52^2-4(16)(-4.5)]/(2*16)=3.33 SEC=3.3 SEC \n" ); document.write( "

\n" );
