Solving MA: Sum of Forces = Mass x Acceleration

AI Thread Summary
To solve for the acceleration of body A using the equation Sum of Forces = Mass x Acceleration, focus on analyzing the forces acting specifically on body A. The first part of the problem has been solved, yielding a mass of 10kg. For part B, it is crucial to correctly identify which free body diagram (FBD) to draw to accurately assess the forces on body A. Properly identifying the forces will lead to the correct calculation of acceleration. Understanding the relationship between mass, forces, and acceleration is key to solving the problem effectively.

Sum of forces = MA

The Attempt at a Solution



I already found the answer to part A, which is 10kg. But for part B I am not sure which box to draw my FBD on.

Since you want the acceleration of body A, analyze the forces on body A.
 

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...
