How do i create the data table to plot the velocity time graph?

......for both the runner and the car?

the velocity of the car is v=cost=4 m/sec
whereas the velocity of the runner is v=a*t=0.5*t

ok what is "cost"?

|dw:1438445437066:dw|

"cost" stands for constant

i mean how did you make the graph without
T(sec) Velocity m/sec
0 0
1 some number
2 some number

is the acceleration along of 20 seconds of time?

i don't know!!! :(

from your text I see that the runner accelerates for 20 seconds

yah....!!!

ok tell me how do i make the data table from velocity and average velocity???

yes....!!!!

i got that....

how do i figure out how far the runner will be in 1,2,3,4,5,6,7,8,9,10,11,12,13,14-20 secods

ok so that car will cover 4 meters every second...got that.

yes!

what about the runner tho :(

what does "s" stand for?

"s(t)" stands for space as function of time

so what does s(t) = 4t means tho???

s(t)=4t, it is the space traveled by the car at time t

so 4 meters?

no, it is:
4*t where t is the time

for example, at t=2, we have:
\[s\left( 2 \right) = 4 \times 2 = 8\]

yah but at 1 second, the runner covered 4meters right since 4X1sec = 4m?????

the car travelled 4*1= 4 meters, whereas the runner travelled 1/4= 0.25 meters

ok so the example that you gave me a second ago was for whome, the runner or the car.....???? car?

ok let me try and i'll get back to you......Thank you and bless you!!! :)

ok i got it...Thanks make gotta wite the formula down.... Peace :)

:)

oh never mind now i see that......i thought you wrote something else.... Cheers!!!!

the answer key suggest 10m/sec at 20 sec.

i need to know how do i make data-table from average velocity in m/sec2

you were given the information already

i want to know how do i make a data table of average velocity.......

|dw:1438452273488:dw|

i keep telling you, your AVERAGE VELOCITY IS your slope

but how do i know how far will the runner be in let's say 7 sec????

|dw:1438452404287:dw|

that is the point when you actually SOLVE it :)

yes yes yes!!! :D

Mary Jesus, Joseph, Muhammad

the car is no problem, it's going at 4m/sec

and?

what does that mean

ok let me ask you a question.....how far will the runner be in 7 seconds????

that is when you solve it
do you know that acceleration is the change in VELOCITY/time ?

|dw:1438452675130:dw|

so acceleration = Velocity/time

|dw:1438452731926:dw|

so by 20 sec, the runner have covered 0.025m????what??????????
