Forces along non-perpendicular axes

AI Thread Summary
The discussion focuses on determining the force components along non-perpendicular axes, specifically calculating the components of F2 along the u and v axes. The calculations yield CompF onto U as 6.93 kN and CompF onto V as -2.07 kN, with the angle adjustments clarified. Participants confirm the calculations are correct, suggesting discrepancies in the provided answers may stem from modifications to the original problem without updating the solutions. The user expresses concern about potentially making a mistake but receives reassurance regarding their calculations. Overall, the thread emphasizes the importance of verifying force component calculations in physics problems.

Determine Force from F2 along u and v axes.
CompF= F*Cos(angle);
CompF onto U = 8kN*Cos(30) = 6.93kN
Angle between F2 and V: 180-75 = 105; 105-30 = 75 degrees
CompF onto V = 8kN*Cos(75) = 2.07 kN. Since in the -V direction; -2.07kN.

I just would like for somebody to verify these answers. I've already missed credit on the problem (Answers shown below), I'm just clueless how they got those numbers.

Your answers are correct. I cannot even figure out what blunder was made in the given answer.
Quite often, it looks like someone modified the numbers in an existing question but failed to update the answer. This one looks weirder.

Thanks for the confirmation! I just wanted to make sure I wasn't going crazy (I'm an undergrad and would be quite nervous if I made a mistake on a question like this) .
 
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...
