Answer 1

car A travels 85.5m in 5 seconds
car B travels 171m in 5 seconds
right?

Answer 2

let me check with the board of trustees

Answer 3

yep your right now the velocity

Answer 4

do you know where i got those distances?

Answer 5

no not really but what do thoes numbers in the green boxes me an and the velocity was b(34.2 and a(17.1

Answer 6

the numbers in the green boxes mean the time

car A travelled one telephone pole length
car B travelled two telephone pole lengths

what is a telephone pole length?

Answer 7

85.5 meters but the numbers in the green boxes what are they for

Answer 8

its only refering to the frames
in the first frame it was 6:31:00
in the 2nd frame it was 6:31:05
its so people dont get confused and assume that the 2 cars started at different times

Answer 9

distance travelled over time is equal to average velocity

Answer 10

i get it by the time the blue car got to the pole the red car sped up enough to be at the pole the same time

Answer 11

your great help can i put another question up as a reply for you to help me on
