If an object is propelled upward from ground level with an initial velocity of 224 feet per second, its height h in feet t seconds later is given by the equation h = 224t - 16t2. After how many seconds does the object hit the ground?
\n" ); document.write( "-------------
\n" ); document.write( "When h = 0
\n" ); document.write( "224t - 16t^2 = 0
\n" ); document.write( "t = 0 (at the start)
\n" ); document.write( "t = 14 seconds
\n" ); document.write( " \n" ); document.write( "

\n" );
