AI Thread Summary
The problem involves calculating the velocity of a particle with acceleration defined as a = g - Kv, where g and K are constants. Starting from rest, the question seeks the velocity after a long time. The discussion raises concerns about whether the velocity will increase indefinitely or stabilize at a constant value. It is suggested that if the velocity approaches a constant, the acceleration would approach zero. The potential answers for the final velocity include g/K, 2g/K, and g/2K.

Homework Statement


Acceleration 'a' of a particle moving in a straight line as a function of velocity 'v' is given as a = g-Kv where 'g' and 'K' are constans . if the object starts from rest then velocity of the object after very long time is ?[/B]

Homework Equations


a= v dv/dx
I don't know exactly what equation should be used

The Attempt at a Solution


Not getting any idea to solve it due to the problem statement which is given as to "calculate the velocity of the object after very long time".
The options given are:
1) g/k
2) 2g/k
3) g/2k
[/B]

Will the velocity increase without limit? What would happen to the acceleration if it did?
If the velocity tends to some constant value, what does the acceleration do?

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 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
