Place yourself facing the edge of an open door. Position your feet astride the door with your nose and abdomen touching the door's edge. Try to rise on your tiptoes. Why can't this be done?

Please help, this is a physics txtbook question found in a chapter about, momentum, impulse, and center of mass. Thank you!

The problem is the number four is outside of the sqrt symbol I dont know what do call it but the four is in the same place a 3 would be if I was trying to figure out the cubed root. Then 81x^4 is on the inside of the sqrt symbol. I hope that made it a little easier to understand

The type Im referring to is a program that can fight off the side of humanity which is increasingly turning evil. Humans just cannot last long enough to stand against the changing mentality of this evolving world. Need to create something which does the right thing. (although I realize right and wrong are relative). Something which can distinguish and defend.
