Algebra.Com's Answer #20717 by hydromojo(20)![]() ![]() ![]() You can put this solution on YOUR website! They've tried to confuse you with the 'six foot person'\r \n" ); document.write( "\n" ); document.write( "You have H = -16T + 729 , where H is the height of the object from the ground.\r \n" ); document.write( "\n" ); document.write( "When the object has hit the ground, H=0, so the formula becomes\r \n" ); document.write( "\n" ); document.write( "0 = -16T + 729, \n" ); document.write( "solving for T, you get 45.56sec \n" ); document.write( " |
