Vector Problem

[warm bloom]

started learning vectors and need more help on understanding

1. Ask your question and show the work you've done so far. If you've posted a screenshot of a question, specify which part you need help with.
2. Wait patiently for a helper to come along.
3. Once someone helps you, say thank you and close the thread with:

   +close
   

4. Feel free to nominate the person for helper of the week in #helper-nominations
5. Do not ping the mods, unless someone is breaking the rules.
6. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

May I assume that we are adding these two vectors?

[warm bloom]

yes

[keen dock]

Then the x-component of the vector sum is the sum of x-components of both vectors

Similarly for y-components

[warm bloom]

would this be the right answer?

[keen dock]

Better state which is on which axis

[warm bloom]

+5 is on x +4 is on y

[keen dock]

Is there a typo?

[warm bloom]

yeah

wiat

wdym?

[keen dock]

Oh there's a mistake in the handwriting

[warm bloom]

yeah it looks like anegative sign

i fixed that

[keen dock]

Yeah that should do

[keen dock]

There isn't a typo then

[warm bloom]

could you show me how to do one more thing? i need to give the magnitude and direction of the vector.

[keen dock]

Could you draw the vector on the xy-plane?

[warm bloom]

is that right?

[keen dock]

We usually draw like this

@warm bloom As you can see, the vector, vertical dotted line and the positive x-axis form a right-angled triangle

That should enable you to find the length (magnitude) of the vector
