Simple Harmonic Motion and Reference Circle

AI Thread Summary
The discussion revolves around a physics problem involving a 3.0-kg block between two springs, focusing on its speed as it passes through the x=0 position and determining the system's angular frequency. The user expresses confusion about how to relate angular frequency to the frequency of cycles and seeks clarification on significant figures in calculations. They attempt calculations but struggle with the correct application of formulas and concepts. The importance of using three significant digits throughout the problem is emphasized. The thread highlights a need for guidance in understanding simple harmonic motion and its mathematical relationships.

Thank you in advance!

Homework Statement


A 3.0-kg block is between two horizontal springs. Neither spring is trained when the block is at the position labeled x=0 m in the drawing. The block is then displaced a distance of 0.070m from the position where x=0m and is released from rest. (a) What is the speed of the block when it passes back through the x=0 position? (b) Determine the angular frequency w of this system.

Homework Equations

How does angular frequency relate to the frequency of cycles?
 
omega!=2pi/T
7.54*10^4= 2pi*f
f=12006
12006*2.5s= 30016 times?
It says to use three significant digits from start to finish. How do I do that? Sorry, I haven't learned this!
Thanks danago!

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...
