Find frequency and period of oscillation

AI Thread Summary
To determine the frequency and period of oscillation for the given pulley system, the radius of the pulley is 2m and the moment of inertia is 10 kg/m². The calculated frequency is approximately 0.982 Hz, resulting in a period of about 1.01 seconds. The calculations involve analyzing the forces acting on the system and applying the principles of rotational dynamics. The user seeks confirmation of their results and a detailed explanation of the calculation process. The discussion emphasizes the importance of understanding the underlying physics to arrive at accurate results.

Homework Statement


Consider the pulley to be ideal. If the system disturbed from its equilibrium position by pulling the right hand mass down a slight amount and then released, determine the frequency and period of the oscillation. Radius of pulley is r=2m and I bar of the pulley is 10kg/m2.

here is the picture:

I got f=0.982hz and T=1.01s

Is that correct?

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
