So j is up, negative j for second force?

[phunphysics2]

Can somebody please check my work? Any and all help is certainly appreciated!

F=ma is used

hi phunphysics2 !

your magnitude is correct, I'm not sure about your direction since i can't see which way you're measuring it

(but you need to write it out much better than this if you're going to pass an exam )

(and i don't understand how you managed to draw a diagram of this without any arrows in it)

Thanks for your response
1. The box is accelerating COMPLETELY to the right. I did not draw in the arrow at 0 degrees but it is noted in the problem
2. I used the standard xy plane for this problem. Origin is in the middle of the box and the arrow Q rests along the 90 degree mark.

The box that I drew was given to us as a picture in the problem

Is the vector notation correct?p.s. I am a 2nd year English major taking calc-engineering physics. Scored 5% higher than the average in class, which was a passing grade

so j is up

then your second force must have negative j

you can either write everything in a continuous string of maths,

or you can write it out as a piece of english

but not as a disjointed collage ​

to calculate the force acting on an object. The letter "j" is typically used to represent force, so when we say "j is up," it means that the force is acting in the upward direction. The negative sign indicates the direction of the force, with a negative value indicating that the force is acting in the opposite direction of the positive value. So in this case, negative j for the second force means that the force is acting in the opposite direction of the first force. It is important to pay attention to the signs in order to accurately represent the direction of the forces involved in a system. As for checking your work, it would be helpful to provide more context or information about the problem in order for someone to accurately check your work.
