A box initially at rest has two forces of eqaul, but small magnitudes applied to it. One force points in the positive y direction, the other in the negative x direction. Which of the following describes the motion of the box? ~The box will accelerate along a line 45 degress clockwise from the -xaxis ~The box will remain at rest since the forces cancel ~The box will move at a a constant velocity along a line 45 degrees clockwise from the -xaxis ~the box will be ripped into two pieces, one goes in the +y direction the other in the -xdirection

I'm pretty sure this is the first or the 3rd one, I just want to be 100% sure and would appreciate explanations

OpenStudy (anonymous):

Your are right. Those are the 2 best choices.

OpenStudy (anonymous):

Newton's first law of motion is often stated as. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

OpenStudy (anonymous):

If two individual forces are of equal magnitude and opposite direction, then the forces are said to be balanced

OpenStudy (anonymous):

|dw:1443410685221:dw| You think its balanced or unbalanced?

OpenStudy (anonymous):

unbalanced? wouldn't it be balanced if say one was in the -y direction and the other was in the positive y direction?

OpenStudy (anonymous):

Yes, +y direction and -y direction of same magnitude are balanced. But this says positive y direction and negative direction with equal magnitude right?

OpenStudy (anonymous):

yeah but one is in the x direction and one is in the y so would they still be balanced?

OpenStudy (anonymous):

Read my explanation before the box diagram.

OpenStudy (anonymous):

They are adjacent to each other, not opposite

OpenStudy (anonymous):

thats basically what i just said

OpenStudy (anonymous):

i'm so confused

OpenStudy (anonymous):

Opposite force and equal magnitude=balanced You said it was balanced. The force acting on the box is not opposite to each other. (Refer to my diagram and question.)

OpenStudy (anonymous):

i said it was unbalanced -_- i just need to know if this is effecting velocity or acceleration.

OpenStudy (anonymous):

yeah but one is in the x direction and one is in the y so would they still be balanced? unbalanced? wouldn't it be balanced if say one was in the -y direction and the other was in the positive y direction?

OpenStudy (anonymous):

2 quotes form you saying it is balanced.

OpenStudy (anonymous):

from*

OpenStudy (anonymous):

Read the last sentence in Newton's First Law of Motion. Change in speed means there is an acceleration. No change in speed means no acceleration.

OpenStudy (anonymous):

I never said ti was balanced you asked is it balanced or unbalanced i answered unbalanced? because if it was opposite it would be -y vs +y . you said correct that -y and +y would be balanced. and i asked would it still be considered balanced since one is up and one is to the left not down vs. up.....

OpenStudy (anonymous):

Oh. Because most people that answers me just say the choices without explanation. I like how you didnt just say the choice. The way you phrased looks like it can have both meanings lol.

Did you read the law?
