Plz help me Practice finding the net force of the following situations. a)
b)
TFnorm=3N
- 3 N
Ffriet=5N
Form
app = 5 N
Ffriet-5N
"gray 3 N
Foray = 3N
Net force:
Net force:
d)
norm- 20 N
Faire 40 N
1***
Foray - 20 N
Foray - 25 N
Net force:
Net force

hey , the answer is c

if you answer my question i will answer yours

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.
