A car travels 20 km South, then turns and travels 30 km East? What is the total displacement?

Explanation:36.05 km

Given

First car travels South

then turns and travels east

Suppose south as negative y axis and east as positive x axis

So,

Displacement is the shortest between initial and final point

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.
