3 slices of a partially eaten 12-inch pizza are shown above. The CM of the entire uneaten pizza is cm = - 1.4 in. and yox= - 1.4 in, as shown.
(a) Assuming that each remaining slice is identical, find the CM of each slice. Choose the origin as shown above.
Starting with the slice in Q2 and going cow give the 3 CM's in the (x, y) format.
HINT: By symmetry, the positions of the CM of each slice must be the same distances x and y from the middle of the
pizza.
(b) Is the crust of the pizza stuffed with cheese? Prove your answer.

answer: strength i guess

explanation:

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.
