Uniform circular motion - simple problem

AI Thread Summary
The problem involves calculating the angular speed of a girl running around a circular fountain with a diameter of 6.5 meters in 72 seconds. The initial attempt at the solution was incorrect, leading to a clarification about the time being 72 seconds rather than 1/72. There was also a light-hearted exchange regarding the notation of π, with one participant humorously commenting on its appearance. The discussion highlights the importance of accurate calculations and notation in physics problems. Overall, the focus remains on solving the angular speed problem correctly.

Homework Statement



A girl is running around a circular fountain with a diameter of 6.5m. If it takes her 72 seconds to run all the way around, what's her angular speed?

The Attempt at a Solution



I appear to be getting a wrong answer: (look only at the thick black marker)

The time is 72 seconds not 1/72.
 
Thanks Doc :) My silly err. you're awesome!
 
Hi Femme_physics! :smile:

Why do you write π like that? :confused:

Shouldn't π have a hat to keep its legs cool? o:)​
 
Heh, you're on to me tiny-tim ;) I don't know how to properly write pi! I'll work on that :-)

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanged 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...
