What the actual fuck.

This question is the most fucked question I have ever seen.


!)
>Magnitude of 10N ......pull crate with constant speed.

The Force is not pulling it if it is constant speed there would be another force to cancel it out.


2) Either that or the the net force is 10N and it is NOT at a constant speed.


3) Forgetting all that and pretending that it is NOT at a constant speed Number One asks for Force Applied NOT net force so it is not simply 10N times 3meters (That was the correct answer in class) You would need to add the Friction plus the net of 10N to get the force applied to get a final answer of around 180J.

4) Number 4 is number 2 (made us cross it out for some other reason)


5) For number five you contradict the answers to number 1 by saying it is Zero. In line with previous questions It would be 10N.


6) Same thing as number 5 but in the form or work All these contradictions.


All these contradictions on a Question that makes no sense in it's entierdy.

I know why my teacher revised this because he probably though the question was to hard for the dumbshits in my class but still wtf. happened.........

I tried explaining this to him and other students but they would't listen or just didn't understand anything ....

Wtf I can't be the only one in my class to understand net forces /sci wtffff?
Am I really arrogant or am I really correct?
