Jim Nazium is walking from lunch to his autoshop class. He exits the lunchroom and walks 62 m west. He then turns and walks 52 m north down the hallway leading to the
workshop. Determine the magnitude and direction of Jim's resultant displacement.
Hint: On your scratch paper, draw a diagram of your vectors. Use tip to tail method.
Draw a dotted line from where he started to where he finishes to make a triangle. Use
the Pythagorean theorem to solve and figure out the magnitude. To solve for the
direction, use the appropriate trig function.

12000j is work done

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.
