Simple Harmonic Motion of an ideal spring

AI Thread Summary
The discussion revolves around calculating the acceleration and maximum extension of an ideal spring with a spring constant of 29 N/m and a 1.4 kg mass attached. To determine the acceleration at maximum extension, the net force acting on the mass must be analyzed. The relevant equation for maximum acceleration is given as a_m = (k/m)A. Participants emphasize understanding the forces involved to solve the problem effectively. The focus remains on applying the correct physics principles to find the required values.

Homework Statement



An ideal spring has a spring constant k = 29 N/m. The spring is suspended vertically. A 1.4 kg body is attached to the unstretched spring and released. It then performs oscillations.
(a) What is the magnitude of the acceleration of the body when the extension of the spring is a maximum?
____ m/s2
(b) What is the maximum extension of the spring?
____ m

Homework Equations



a_{m}=\frac{k}{m}A

The Attempt at a Solution



I don't know how to start this problem. Any help?

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...
