Aperson of mass 81.63 kg (weighs 800 n) wants to climb a ladder to perform a stunt on the icy surface of lake champlain. there is no friction between the feet of the ladder and the surface of the ice. assume that the mass of the ladder is small enough that it can be ignored. each half of the ladder has a length of 2.5 m, and the two halves are joined together by a 70 cm tie rod connecting the midway points of each side. if the person stands 3/5 of the way up the ladder, what is the tension in the tie rod? be sure to enter units in your answer.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
