g Lightly mark the top side of the friction block not in contact with the wooden board for later reference. Place the 500 g hanging weight on top of the friction block. Calculate the sum of the masses of the 500 g hanging weight and the friction block. Convert the sum of the masses in step 7 to weight using the conversion w

answer :

b

explanation:

powerful computers now, not then

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.
