A cyclist maintains a constant velocity of 5.6 m/s headed away from point A. At some initial time, the cyclist is 245 m from point A. What will be his displacement from his starting position after 58 s? Answer in units of m

Is it accepted as the correct answer???

OpenStudy (anonymous):

yes it is do you know what will be his position from point A after that time? answer in units of m

OpenStudy (isaiah.feynman):

After what time?

4 years ago
OpenStudy (anonymous):

58 seconds I believe

His position at that time you gave will be x2 = 324.8m. He started at x1 =0 and ended up at x2 =324.8m

wait so the 245 doesn't matter?

OpenStudy (isaiah.feynman):

For that question it doesn't matter.

OpenStudy (anonymous):

well then why is it part B for this question? lol I mean you may be right but I don't understand why it would be the same answer

OpenStudy (isaiah.feynman):

Maybe to see if you understand what position and displacement means.

OpenStudy (anonymous):

Maybe you're right

OpenStudy (isaiah.feynman):

Anyway, check to see if that position answer is right!

OpenStudy (anonymous):

Nope it's wrong

OpenStudy (isaiah.feynman):

Then maybe they don't mean after 58 seconds.

4 years ago
OpenStudy (anonymous):

maybe we add the 245?

4 years ago
OpenStudy (anonymous):

Yay it was right :D

4 years ago
OpenStudy (isaiah.feynman):

What was right?

4 years ago
OpenStudy (anonymous):

adding 245 to 324.8

4 years ago
OpenStudy (isaiah.feynman):

Doesn't make sense though.

OpenStudy (anonymous):

Noooo idea I just know it worked. I think it's cuz it started with it already being 245 m away from A then after 58 secs it was further

4 years ago
OpenStudy (isaiah.feynman):

Ohhh in that case you calculate the distance covered in 58 seconds then add it to 245 and that would give five hundred and something...

4 years ago
OpenStudy (anonymous):

yep that's the right answer to the second part

OpenStudy (isaiah.feynman):

Ok.
