William is walking straight across a field towards a vertical flagpole .He observes that when he is at point A ,the angle of elevation of T, the top of the flagpole is 30degrees and when he is at point B, on the same side of the flagpole as A, the angle of elevation of T is 45degrees .The distance between A and Bis 20 metres . Using a scale of 1cm to represent 4m ,construct a single diagram to show the relative positions of A, B and T .b. Using a suitable construction on the same diagram, find the height of the flagpole

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.

the answer is a. hope this .
