AI Thread Summary
A racer traveling 3.70 meters in one second raises the question of how long it takes to cover 2(3.70) meters. The initial assumption of 2 seconds is challenged by the book's suggestion of the square root of 2 as the correct answer. The discussion hints at the need for clarification regarding whether the racer is moving at a constant velocity or experiencing uniform acceleration. It is emphasized that the context of the motion significantly impacts the calculation. Understanding the conditions of the racer's movement is crucial for determining the correct time.

If a racer travels 3.70m in one second. How long does it take for the racer to travel 2(3.70)m?

I was expecting 2s as the result but the book suggests square root of 2 to be the answer. I don't know why? Can anyone help me please.

Welcome to the PF.

Is the racer accelerating? What is the exact quote from the book?
 
Thank you! That's all the information given on the book. I suppose he's moving inthe constant velocity
 
I can only suggest you double check that you have quoted the question word for word as given in the book.
 
triple checked ;p

That won't work.

Assume uniform acceleration starting from rest.

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...
