This is not a traditional homework question:

Anyone familiar with the the U texas homework will understand:

Does anyone have the answer key to the utexas physics homework on rotational motion?
Our teacher hasn't taught us anything on rotation. We are desperate to know how to do these problems for our test next week. Please if anyone has the answers let me know and hopefully you can help an entire physics class pass their exam and send us the pdf.

Maybe you should just ask a question about the problems you need help working, rather than ask for the answer sheet. I graduated from UT-Austin a few years back and I might be able to help you, but I need a specific question, not just a general request for an answer sheet.
 
The problem is that its due tomorrow night and none of us have a clue how to do it, we are in school all day, so time is pressured.
 
Gee, I guess that's tough then.
 
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 .
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...
