First, welcome to OpenStudy!! If any object ends up in the same place in which it started, it's displacement must be 0. Remember that there's a big difference between displacement and distance. The book traveled through a distance equal to the perimeter of the table...but since it's back where it started, it's displacement was 0.
Thank you so much!
No problem :)
what would be the distance traveled?
What do you calculate the perimeter of the table to be? That's your answer :)
:) do you know how many questions i can ask?
As many as you like!
The distance you should get is 8m
oh my god! thanks! are you willing to help me with like 29 questions or less if i can get the hang of it?
If not me I'm sure someone will. Just post each one separately and give medals to those that help you :)
how do you give medals? this is my first time joining
Click the "Best Response" button...that's it
oh ok.. so are you a paid tutor? how does this work?
This site is completely free. 99% of the people here are no paid and just like helping others.
are *not* paid...typo
wow that is so nice! so i have more questions, is that alright?
Yes, just post them as new questions. One main question per thread
okay, what is bump?
I believe that bumps your question to the top...my screen doesn't show it but I don't ask questions...just try to help others
that is so nice :)
Helping folks keeps me from forgetting all this stuff...so I get something out of it too :)
if the average speed of an orbiting space shuttle is 19400 mi/h, find the time required for it to circle earth. consider the fact that the shuttle is orbiting about 204.6 mi above earths surface, and assume that earths radius is 3963 mi. answer in of h
Post it as a NEW question :) Look up to the left of your screen and paste that into the "Ask a question" box
More people will see it that way :)
okay thanks so much for your time shane
For this last question just think of circles. 1) Add the height above earth to the radius to get the total radius of the orbit 2) Calculate the perimeter of the orbit based on this new radius (Circumference = 2 pi R). 3) Divide the speed by the circumference to get the time it takes it takes to circle the earth once
thanks that helps a lot
