If an object is thrown upward with an initial velocity of 16 ft/sec, its height, h, in feet, after t seconds is given by h=16t-16t^2 Find the number of seconds before the object hits the ground. (Round your answer to the nearest tenth, if necessary.)
\n" ); document.write( "-----------------
\n" ); document.write( "It hits the ground when h = 0
\n" ); document.write( "h=16t-16t^2 = 0
\n" ); document.write( "t = 0 (when it's starts)
\n" ); document.write( "t = 1 second at impact
\n" ); document.write( "
\n" ); document.write( "
