Create a Rolling Device Powered by Rubber Bands - Help Josh!

AI Thread Summary
The discussion revolves around a physics project requiring the creation of a rolling device powered solely by rubber bands, using a coffee can or similar as the main structure. Participants suggest looking at existing designs, such as balloon cars, for inspiration on how to effectively utilize rubber bands for propulsion. The project emphasizes the importance of speed and distance during testing in class. Suggestions include adjusting and winding the rubber bands to optimize performance. Overall, the conversation focuses on brainstorming ideas and sharing resources to help Josh succeed in his assignment.

Well i have been assigned a project in my physics class that is totally clueless to me so i have come to all you smart peoples to help me with it because I am like totally clueless of what to do...

I am to create a rolling device powered by (a) rubber band(s) (no engines, etc)

Guidelines...
-- The tin can has to be a coffee can or similar
-- The rolling device has to be powered by (a) rubber band(s)
-- To make the rolling device operate, you may adjust, wind, etc. the rubber band
-- You may use other material to help your rolling device operate

Anybody have any idea on how to make something good? When we test these in class, we will be looking for speed and distence.

Please help
Thanks
Josh

Ah nice find man, thanks a lot!

I'll check that out right now :)
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
