a and b*
Vector form is i and j, i represent x direction j represent y direction. like 5i+6j is 5 coordinates to the right and 6 to the north. -5i-6j would be 5 coordinate to the left and 6 to the south.
what are the scalars for i and j of the resultant?
I know how to do this but keep getting the wrong answer for some reason.
Angle 1 and 3 are corresponding angles so they are the same. Subtract 180 degrees from the (angles of 2 and 3) to get angle 5.
cos30=x/11.7 so 11.7cos30=x You would get the x component for vector A sin30=y/11.7 so 11.7sin30=y You would get the y component for Vector B
Now try to get the x and y component for vector B. After you get both, you would add the x component of vector A and B together to get the displacement or resultant x component. Then do the same to get the resultant vectors y component.
That's the one I'm having trouble with Vector B
For vector A we can definitely do what you said, but not for vector B because it has a 106 degree angle.
Either that or my calculator is stupid.
ok so 164
ahhhh i see
Take that back.
I got -1.1 for the I of the resultant
Then what is it?
Nevermind, it works.
What do you get for the i and j values of the resultant?
How did you get 164 if you add 90 angles to angle 5?
angle 5 is 74
5,3 and 2 must add up to 180
Show me your math.
On how you get 74
Actually I can't even remember how I got to 74 now that I think of it.
oh yea 180=106
Thats only 2. You wrote angle 5,3,2 must add up to 180.
nvm on that.
5, and 2 must add up to 180
You were right on that. And I said your 74 degrees on angle 5 is wrong. Look at my drawings again.
then how do i find 5 and 2?
Look at your problem and information, not given by me.
That picture plus the words are the only information.
What is angle 3?
that doesn't help
and how do you know it is 30 degrees. Wait up and you will see ok?
It's a geometry rule.
And how did you know angle 1 is 30 degrees?
So what is angle 2?
I have no idea
oh is that the 106?
Ok so I figured that out angle 5 is 44
But how did you know angle 1 is 30 degrees? Please reread. -_-
It's a given
Yes it is 44
Whenever there is an angle that is not 0 or 90 or 180 degrees, I do not just assume the angle number. It has to be given by the information.
I cant just guess that angle 1 is 30 degrees without info.
angle 1 is 30 that's a given.
Yes, so you should have no trouble knowing what angle 2 is. Always read your question and information carefully. It helps a lot in physics.
If I dont know what angle 2, I would not figure out how to do this.
