A baseball is thrown from a stadium seat and its path is shown by h(t)=-16t^2+75, where h is height in feet and t is time in seconds.\r
\n" ); document.write( "\n" ); document.write( "A. How long before the ball hits the ground. Round to hundredths
\n" ); document.write( "h(t)=-16t^2+75
\n" ); document.write( "It hits the ground when h(t) = 0
\n" ); document.write( "-16t^2+75 = 0
\n" ); document.write( "Solve for t
\n" ); document.write( "===============================
\n" ); document.write( "B. How high off the ground is the stadium seat?
\n" ); document.write( "h(t) at t = 0
\n" ); document.write( "
\n" ); document.write( "
\n" );
