Angular velocity and acceleration

AI Thread Summary
The discussion focuses on solving a physics problem involving a block moving left with a constant velocity. The user seeks assistance in determining the distance x as a function of angle Q, along with the angular velocity and angular acceleration as functions of Q. They have derived an equation for distance x but are unsure how to proceed with finding angular velocity and acceleration. The user inquires whether taking the first and second derivatives of x will suffice for these calculations. The conversation emphasizes the need for clarification on the relationship between linear and angular motion.

Homework Statement



The block moves to the left with a constant velocity v.

a)determine the distance x as a function of Q .
b)determine the Angular velocity as a function of Q
c)determine the Angular acceleration as a function of Qhttp://img98.imageshack.us/img98/3691/16293179.jpg

Homework Equations


The Attempt at a Solution

Here is how i find the distance x. tagQ=a/x -> x=a/tagQ .
Can anybody help me a little bit how to find b). Is it enough just to find the 1-st and 2-nd derivative of x in order to find velocity and acceleration ?

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...

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...
