    Height Ramp
AI Thread Summary
The discussion focuses on how the ramp angle affects the maximum height a block reaches when shot up a slope. A block is initially shot up a 40-degree frictionless slope, reaching height h, and then shot up a 20-degree slope with the same speed. Participants suggest using the conservation of energy principle, specifically kinetic energy (KE) and potential energy (PE), to determine the height without needing to calculate speed directly. The conversation emphasizes the importance of understanding energy conservation in relation to different angles. Overall, the key takeaway is that the ramp angle influences the height reached, and energy conservation can simplify the analysis.

Homework Statement


A block is shot up a frictionless 40degree slope with intial speed v. It reaches height h before sliding back down. The same block is shot with the same speed up a frictionless 20 degree slope. On this new slope, the block reaches height?

Hi girlsnguitars! :smile:

You don't need speed (except that you want the height at which the speed is zero :wink:).

Just use KE + PE = constant. :smile:

Hi,
would you mind posting your answer when, or if, you get it? Thanks
 

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'

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...
