Homework Help Overview

The discussion revolves around converting a Speed vs Time graph of an airplane taking off into a Position vs Time graph. The subject area involves concepts of kinematics and graph interpretation.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the need to convert units to a consistent system and explore the relationship between speed and displacement. There are attempts to clarify how to derive position from speed, with some participants questioning the appropriate unit conversions and methods for plotting the graph.

Discussion Status

The discussion is active, with participants providing guidance on unit conversion and the geometric interpretation of the graph. There are multiple interpretations regarding the conversion process and the relationship between speed and position, indicating a collaborative exploration of the problem.

Contextual Notes

Some participants express uncertainty about the units and the initial steps needed to approach the problem. There is a mention of the original poster's limited background in physics, which may influence the discussion dynamics.

None

The Attempt at a Solution


Don't know where to begin... Please help! I have Graph paper and will make the PvT graph on there. I am only in 8th grade and know barely any Physics.

Sorry, It's here now!
 
first thing bring both qtys into SI or any particular system you want.(careful about the units) .

now think geometry and graphs
what is the relation between displacement and speed. How can you relate the quantities given and get displacement(which is as good as position starting from origin in this case).

Get values of displacement for t=1,2,3 and so on and plot them on your graph.
you should get a curvy(parabolic) figure.

SI? What's that?
 
ah just a system of units for measuring...
http://en.wikipedia.org/wiki/International_System_of_Units

Name Unit symbol
metre m length
kilogram kg mass m
second s time tThe above will be important for you. convert the speed into miles/seconds(or meter/second if you wish) which originally in miles/hour.

Then solve..
 
The speed to miles per second... so would i just multiply the speed by 60²? And after doing that, how would I change the speed to position? Would I divide the time by the speed to get it?
 
I'm actually now thinking I should divide by 60²
