Horizontal force on a post in a Hammock

AI Thread Summary
The discussion focuses on calculating the horizontal force exerted on two vertical posts by a person sitting in a hammock. It establishes that the mass of the person, the distance between the posts, and the dip of the hammock are critical factors in determining this force. The gravitational constant is denoted as g, which plays a role in the overall force calculations. The physics principles involved include tension and equilibrium in the system. Understanding these forces is essential for ensuring the stability of the hammock setup.

Your friend of mass m sits in a hammock that is suspended between two vertical posts separated by a distance d. If the hammock dips a distance h below the height l at which the hammock is secured to the posts, what is the horizontal force on each post due to your friend? Use g for the gravitational constant.

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...
