Lab for finding acceleartion vectors for circular motion

AI Thread Summary
The discussion revolves around understanding how to represent the change in velocity vector for circular motion, specifically transitioning from V0 to V1. The user is confused about how to visually depict this change and is seeking guidance. It is clarified that the change in velocity can be calculated as V1 - V0, indicating a focus on vector addition and subtraction. There is also uncertainty about whether the main homework question is indeed about finding this change in velocity or if it pertains to a broader topic. The conversation emphasizes the importance of correctly visualizing vector changes in physics problems.

Homework Statement


I am trying to draw a change in velocity vector connecting from V1 to -V0, but I can't seem to figure it out. How do I show you guys what my problem is?

The change in velocity is simply V1-V0, assuming the velocity changes from V0 initially to V1. So this is a problem in vector addition/subtraction.

Is the actual homework question to find the change in velocity, or is this just a question along the way to something else?
 
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...
