5.How far must a 5 N force pull a 50 g toy car if 30 J of energy are transferred?

5 meters

Explanation:

Step one:

given data

mass of the toy car= 50g

Work done= 30J

Force applied F= 5N

Required

The distance moved

Step two:

The expression for the work done is given as

WD= force * distance

substitute

30= 5*d

divide both sides by 5

d=30/5

d= 5m

The distance moved is 5 meters

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.
