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 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
