Question

please help! Calculating velocity! picture below!

Answer 1

I cant determine where segment A is ending..i know velocity=distance/time though

Answer 2

@tesla117 can you help at all?

Answer 3

This type of graph is in a linear format so to calculate the velocity you would do

(ending position - starting position) / (ending time - starting time)

for the first one (looks like it's 25seconds until it goes flat)...

( 10 meters - 0 meters ) / ( 25 seconds - 0 seconds) = 10/25 = .4 meters/sec

The rest I'll leave to you unless you can't figure it.

Answer 4

Would the velocity for segment B just be 0? since no distance is being covered?

Answer 5

That is correct I believe the graph was meant to be linear so using the same equation

(10m - 10m) / (35-25) = 0/10 and we know zero divided by a number is 0

Answer 6

okay thank you! and the segmet C would be....30 m/s?

Answer 7

so plugging the numbers in

(30 m - 10 m ) / (60 s -35 s) = (20/25) = .8 m/s

Answer 8

okay im confused! haha isnt velocity just distance/time?

Answer 9

what is the whole ending point starting point? i havent learned anything like that! haha just the v=d/t

Answer 10

Correct think about your response if you where going 30m/s then in the 25 secs you would have traveled over 750 meters!

v =d/t is correct and the same thing as the equation I have used but you have to think about it...

when you divide each segmanet you get a certain distance which you call "d" which is a real number value say in the section A you d = 10

but to solve for d

d = (ending position - starting position)
t = (ending time - starting time)
