please I'll medal and fan I just need help understanding how to do it
Omg I'm doing that right now it's so confusing 😪
go to khan academy.
Or give your thoughts where are you sticking
I'm not scared to do a little work I just need some basic help on what their asking
Which question are you stuck on?
like when it says what the length of\ the x- component does it mean like 8 because its 8
1. Length of x component is x2-x1. Did you solve that already? I see your work at the bottom of the graph.
that's what I'm trying to figure out how did you find the length
It is correct.... 9-1=8 8 is length ??
oh yea thats what was already written their I didnt put that their
but thats what I was thinking
This is more like pre algebra. If you are taking physics you should know this. x2-x1=9-1=8
and y2-y1=10-4=6 Do you see the x and y components in the triangle?
ok so then for the first two lines I write like 8 for x component and 6 for y component
Foe 3. a^2+b^2=c^2 Know this?
and then I do the Pythagorean theorem do I set it up like this 8^2 +6^2 yea i know Pythagorean
What did you get for length?
I got what I told you 8 for x 6 for y
That would be your displacement vector. Displacement is (endpoint-starting point)
For 3. Of course I know that.
So for three what am I doing then
Omg my computer is so slow is there any other way we could talk
here my ipad number is 8175768395
Foe 3. a^2+b^2=c^2 Know this? I put that earlier, bit I made a typo. It should be "For 3."
yea that Pythagorean theorm
Ex: for 4. means that I am helping you with problem 4. Understand? I do it by order.
I do the next problem after you are finished. You were finished with 1 and 2 and now I am doing 3 with you.
For 3. a^2+b^2=c^2 Solve for c since we have a and b already.
ok thank you so are we plugging in numbers now
Yes, do you remember pythagorean theorem?
of course thats like the easiest to do
so would it be plug in 8 and 6 to find c
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?
Yes, you would plug 8 and 6 to find c
yes its a right triangle so it would be 8^2+6^2=c?
ok so 8 time 2 equales 64 then 6 time 2 equals 36 add them i get =100
square root of 100 is 10
yes. that is displacement. Displacement is like the distance between your ending point and starting point.
For 4. what is distance traveled and what is your displacement? Then you would compare them. Pretty common sense in this question.
ok so my displacement is 10 and
14 is the distance
Yes, that is the answer. Well, you got to put it in sentence.
ok so my distance 14 is greater than my displacement which is 10.
The lab you can do by yourself. It is easy if you review what I taught you.
Lets go to conclusion now.
For 1 a). it is common sense. 1 b). ending point-starting point.
1 b) final position-initial position.
those questions arent on her?
Scroll down. It is.
i think he ended it at 14m
ok so for the conclusion the distance he travaled i think would be 14 km or do I add like
How? Distance traveled=total distance traveled.
Read the problem again.
he travled 9km then went back 4km and then turns around again and travels 14km
So what is your answer?
Total distance=amount of distance the truck traveled (includes every distance)
