    Graph Impulse
AI Thread Summary
The discussion revolves around calculating impulse from a force graph for a 3.0 kg particle. The initial attempt involved summing the areas under the force curve but resulted in an incorrect value of 5000 N s. Participants noted that the error might stem from a misunderstanding of units, specifically confusing seconds with milliseconds. This realization led to a correction in the approach to calculating impulse. The conversation emphasizes the importance of unit consistency in physics calculations.

Homework Statement



What is the impulse on a 3.0 particle that experiences the force shown in the figure (Figure 1) ?
Figure 1:

Homework Equations


Impulse equations, force equations, how they relate.


The Attempt at a Solution


I added the area above the x-axis for the time interval 2 to 8 and subtracted the areas from 0 to 2 and 8 to 10. This answer came out to be 5000 N s which is incorrect. I'm confused because I thought the integral of force (the area bounded by the force graph) is equal to impulse.

Help would be greatly appreciated. :smile:

Your result seems too large. s vs ms, perhaps?

Yes! I can't believe I didn't think of that. Thank you!
 

Thread 'Rolling without slipping on a curved surface'

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...
