Question

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

Answer 1

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

Answer 2

go to khan academy.

Answer 3

Or give your thoughts where are you sticking

Answer 4

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

Answer 5

Which question are you stuck on?

Answer 6

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

Answer 7

@diracdelta

Answer 8

@Sophilou

Answer 9

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

Answer 10

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

Answer 11

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

Answer 12

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

Answer 13

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

Answer 14

but thats what I was thinking

Answer 15

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

Answer 16

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

Answer 17

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

Answer 18

That works.

Answer 19

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

Answer 20

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

Answer 21

Yes.

Answer 22

What did you get for length?

Answer 23

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

Answer 24

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

Answer 25

For 3.
Of course I know that.

Answer 26

So for three what am I doing then

Answer 27

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

Answer 28

here my ipad number is 8175768395

Answer 29

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

Answer 30

yea that Pythagorean theorm

Answer 31

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

Answer 32

ok

Answer 33

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

Answer 34

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

Answer 35

ok thank you so are we plugging in numbers now

Answer 36

Yes, do you remember pythagorean theorem?

Answer 37

of course thats like the easiest to do

Answer 38

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

Answer 39

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?

Answer 40

Yes, you would plug 8 and 6 to find c

Answer 41

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

Answer 42

yes

Answer 43

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

Answer 44

square root of 100 is 10

Answer 45

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

Answer 46

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

Answer 47

ok so my displacement is 10 and

Answer 48

14 is the distance

Answer 49

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

Answer 50

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

Answer 51

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

Answer 52

That works.

Answer 53

Lets go to conclusion now.

Answer 54

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

Answer 55

1 b) final position-initial position.

Answer 56

those questions arent on her?

Answer 57

Scroll down. It is.

Answer 58

i think he ended it at 14m

Answer 59

@Shalante

Answer 60

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

Answer 61

How?
Distance traveled=total distance traveled.

Answer 62

Read the problem again.

Answer 63

he travled 9km then went back 4km and then turns around again and travels 14km

Answer 64

So what is your answer?

Answer 65

Total distance=amount of distance the truck traveled (includes every distance)
