OpenStudy (crazypizzalover):

please I'll medal and fan I just need help understanding how to do it

OpenStudy (crazypizzalover):

OpenStudy (anonymous):

Omg I'm doing that right now it's so confusing 😪

OpenStudy (anonymous):

OpenStudy (anonymous):

Or give your thoughts where are you sticking

OpenStudy (crazypizzalover):

I'm not scared to do a little work I just need some basic help on what their asking

OpenStudy (anonymous):

Which question are you stuck on?

OpenStudy (crazypizzalover):

like when it says what the length of\ the x- component does it mean like 8 because its 8

OpenStudy (crazypizzalover):

@diracdelta

OpenStudy (crazypizzalover):

@Sophilou

OpenStudy (crazypizzalover):

OpenStudy (anonymous):

1. Length of x component is x2-x1. Did you solve that already? I see your work at the bottom of the graph.

OpenStudy (crazypizzalover):

that's what I'm trying to figure out how did you find the length

OpenStudy (crazypizzalover):

......................

OpenStudy (anonymous):

It is correct.... 9-1=8 8 is length ??

OpenStudy (crazypizzalover):

oh yea thats what was already written their I didnt put that their

OpenStudy (crazypizzalover):

but thats what I was thinking

OpenStudy (anonymous):

This is more like pre algebra. If you are taking physics you should know this. x2-x1=9-1=8

OpenStudy (anonymous):

and y2-y1=10-4=6 Do you see the x and y components in the triangle?

OpenStudy (crazypizzalover):

ok so then for the first two lines I write like 8 for x component and 6 for y component

OpenStudy (anonymous):

That works.

OpenStudy (anonymous):

Foe 3. a^2+b^2=c^2 Know this?

OpenStudy (crazypizzalover):

and then I do the Pythagorean theorem do I set it up like this 8^2 +6^2 yea i know Pythagorean

OpenStudy (anonymous):

Yes.

OpenStudy (anonymous):

What did you get for length?

OpenStudy (crazypizzalover):

I got what I told you 8 for x 6 for y

OpenStudy (anonymous):

That would be your displacement vector. Displacement is (endpoint-starting point)

OpenStudy (anonymous):

For 3. Of course I know that.

OpenStudy (crazypizzalover):

So for three what am I doing then

OpenStudy (anonymous):

Omg my computer is so slow is there any other way we could talk

OpenStudy (crazypizzalover):

here my ipad number is 8175768395

OpenStudy (anonymous):

Foe 3. a^2+b^2=c^2 Know this? I put that earlier, bit I made a typo. It should be "For 3."

OpenStudy (crazypizzalover):

yea that Pythagorean theorm

OpenStudy (anonymous):

Ex: for 4. means that I am helping you with problem 4. Understand? I do it by order.

OpenStudy (crazypizzalover):

ok

OpenStudy (anonymous):

I do the next problem after you are finished. You were finished with 1 and 2 and now I am doing 3 with you.

OpenStudy (anonymous):

For 3. a^2+b^2=c^2 Solve for c since we have a and b already.

OpenStudy (crazypizzalover):

ok thank you so are we plugging in numbers now

OpenStudy (anonymous):

Yes, do you remember pythagorean theorem?

OpenStudy (crazypizzalover):

of course thats like the easiest to do

OpenStudy (crazypizzalover):

so would it be plug in 8 and 6 to find c

OpenStudy (anonymous):

It is a right triangle and you are trying to find displacement vector. You got the x and y components. You do know they tell you hints in the worksheet right? Have you passed Algebra yet?

OpenStudy (anonymous):

Yes, you would plug 8 and 6 to find c

OpenStudy (crazypizzalover):

yes its a right triangle so it would be 8^2+6^2=c?

OpenStudy (anonymous):

yes

OpenStudy (crazypizzalover):

ok so 8 time 2 equales 64 then 6 time 2 equals 36 add them i get =100

OpenStudy (crazypizzalover):

square root of 100 is 10

OpenStudy (anonymous):

yes. that is displacement. Displacement is like the distance between your ending point and starting point.

OpenStudy (anonymous):

For 4. what is distance traveled and what is your displacement? Then you would compare them. Pretty common sense in this question.

OpenStudy (crazypizzalover):

ok so my displacement is 10 and

OpenStudy (crazypizzalover):

14 is the distance

OpenStudy (anonymous):

Yes, that is the answer. Well, you got to put it in sentence.

OpenStudy (crazypizzalover):

ok so my distance 14 is greater than my displacement which is 10.

OpenStudy (anonymous):

The lab you can do by yourself. It is easy if you review what I taught you.

OpenStudy (anonymous):

That works.

OpenStudy (anonymous):

Lets go to conclusion now.

OpenStudy (anonymous):

For 1 a). it is common sense. 1 b). ending point-starting point.

OpenStudy (anonymous):

1 b) final position-initial position.

OpenStudy (crazypizzalover):

those questions arent on her?

OpenStudy (anonymous):

Scroll down. It is.

OpenStudy (crazypizzalover):

i think he ended it at 14m

OpenStudy (crazypizzalover):

@Shalante

OpenStudy (crazypizzalover):

ok so for the conclusion the distance he travaled i think would be 14 km or do I add like

OpenStudy (anonymous):

How? Distance traveled=total distance traveled.
