Question

Over which interval is the velocity greatest?

Answer 1

i looooooove one direction<3

Answer 2

haha sorry for trollin

Answer 3

vl=displacemnt/time.....so u count squares for dis and divide it by time squares...for each straight line of graph which is changig will give the answer.

Answer 5

why did u call so many people

Answer 6

cause half of them dont come

Answer 7

oh

Answer 8

il try to help

Answer 9

yah so i figured the more the better cause someone might know how to help

Answer 10

what grade u in

Answer 11

welll 8th but that doesnt have to do with the question

Answer 12

im and 7th and i dont understand da question

Answer 13

velocity = displacement/time or in this case v=d/t where d is the distance
therefore, the time with the biggest slope should be the greatest velocity which is (0,3)

Correct me if I'm wrong for any reason...

Answer 14

*time interval

Answer 15

is the biggest slope a

Answer 16

it's A->B I'm not sure if A is pointing at the 0 mark or the line segment...

Answer 17

hmm yah i see what your getting at

Answer 18

A:B is the greatest acceleration.

However, I see C:D as having the greatest velocity of 6m/s over 8 seconds.

Answer 19

well its asking for the greatest velocity so would that be c d

Answer 20

Yup! That's what I would mark, :-)

Answer 21

Clarification question: Does that graph show the distance from a fixed point of an object?

Answer 22

ok thank you could you ehlp em with a couple other questions using the same graph

Answer 23

if u know what velocity means u will get the answer

Answer 24

well my question if you want ot help is over which interval is the velocity zero

Answer 25

I see no interval where the velocity is zero.

Answer 26

thats why im confused

Answer 27

Confused about what?

Answer 28

\[\vec{v} = \frac{\vec{r}}{t}\]

I dont understand what your not understanding.

Answer 29

cause i see no interval fo zero so i dont know what to answer it as

Answer 30

Can you show us a source for the questions you're asking?

Answer 31

if \[|\vec{r}| = 0 \implies |\vec{v}| = 0\]

so look for where the graph is flat to find sections of 0 velocity.

Answer 32

its just that graph and this question so yah

Answer 33

A flat line would indicate 0 acceleration, not zero velocity.

Answer 34

its probably c - d because its the only thing that doesnt increase or decrease

Answer 35

I thought the flat line indicates no change in any rate so the displacement would be 0 right? or is that wrong?

Answer 36

Is this a multiple choice question?

Answer 37

nope

Answer 38

its a blank that u fill in

Answer 39

True enough, @AnElephant.

The flat line in the graph is maintaining a speed of 6m/s for 8 seconds - and that is a "velocity".

Zero distance over time is zero velocity, and their are no segments that show zero distance.

Answer 40

ah nevermind then, i thought the graph showed the particle or whatever staying at a constant distance of 6 for however many seconds there were

Answer 41

Well, I'm not enrolled in any of these courses so I can't speak with authority, but *IF* I were, and IF I had this question, I would fill in that there are no segments showing zero velocity.
