    Motion Period
AI Thread Summary
The discussion focuses on calculating the period of motion for a piston with a mass of 0.85 kg, modeled as simple harmonic motion. Given the acceleration of 8 m/s² when the piston is 10 cm from the midpoint, the formula a = -(2πf)²x is applied to find the frequency. Participants suggest rearranging the equation to solve for frequency (f) and subsequently determining the period (T) using the relation T = 1/f. The calculated velocity of 1.26 m/s is mentioned, but its necessity for finding the period is questioned. Ultimately, the key objective is to derive the period of the piston's motion based on the provided parameters.

The movement of a particular piston of mass 0.85kg may be modeled with a simple harmonic. Given that its acceleration is 8m/s when 10cm from the mid position. Find the period of the motion??

I found velocity to = 1.26m/s, but I am not even sure if i need to calculate the velocity.

a=-(2πf)2x

We have a (= 8 m/s)
We know 2π (constant)
And we know x (= 10cm)

Rearrange to find f.

Period = 1/f

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...
