The force with which I push down on the Earth is PRECISELY equal to the force with which the Earth pushes UP on me.
I weigh EXACTLY the same amount on the Earth as the Earth weighs on me. Find THAT amount, and you'll have the answer to the question.
(Hint: 1 kg is a mass, and 2 pounds is a force, so they can never be equal. 1kg weighs about 2.2 pounds IF it happens to be on Earth. But if the same 1kg is on the Moon, then it weighs about 5.8 ounces. And if it happens to be on Mars, then it weighs about 13.3 ounces. The same kilogram weighs different weights in different places.)
On a good day, I push down on the Earth with about 890 Newtons of force. No matter how hard I try, I can never push more or less than that.
