Simple Harmonic Motion equation rearrangement?

AI Thread Summary
To calculate free-fall acceleration (ag) from the period of a simple pendulum, the equation T=2π√(l/g) needs to be rearranged. By isolating g, the formula becomes g = (4π²l) / T². Using the provided values of length (1 meter) and period (20.1 seconds), one can substitute these into the rearranged equation to find ag. The user successfully solved the problem after seeking assistance. Understanding the rearrangement of the pendulum equation is crucial for accurate calculations in physics experiments.

Homework Statement


Hello! I have a physics homework question I just need help at!
What I am supposed to do is calculate the value for free-fall acceleration, ag, for each of my trials that I did in my lab. I supposed to use the equation for the period of the simple pendulum, T=2π√l/g, but I have to rearrange it to solve for ag. How would I do that?

Homework Equations


Here are some sample values I used in my lab:
Length: 1 meter
Period: 20.1 seconds

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...
