Simple harmonic motion , Particle

AI Thread Summary
The discussion revolves around solving a homework problem related to simple harmonic motion (SHM) involving a 150-gram particle oscillating 24 cm with an average speed of 60 cm/s. Key questions include determining the angular frequency, maximum force, and maximum speed of the particle. Clarification is sought on the meaning of maximum force and whether weight is necessary for calculations. The response emphasizes that SHM involves acceleration proportional to the negative distance and confirms that weight is only needed for calculating maximum force. The conversation highlights the importance of understanding the principles of SHM to solve the problem effectively.

Homework Statement



A 150 grams particle oscillating in SHM travels 24 cm between the two extreme points in its motion with an average speed of 60cm/s

Find
a) angular frequency
b) the maximum force on the particle
C) the maximum speed


The Attempt at a Solution



My first question would be what approach to use ?? This is the first problem I do with a particle. I am having trouble just finding the angular frequency and I don't even know if am suppose to use the weight for the first answer.

My second question is , what do they mean by maximum force on the particle ?
is it somewhat like a spring Fsp = kx ?

Hi EvilBunny! :smile:

SHM means the acceleration is proportional to (minus) the distance …

x'' = -kx.

You should be able to get everything from that (and no, you only need the weight for part b). :smile:
 

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

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 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...
