    Change Displacement
AI Thread Summary
To calculate the change in R or displacement, it's essential to clarify the context of R and the specific type of displacement being referred to. Common formulas include those derived from differential calculus and Newton's laws of motion. Examples of calculations can involve determining velocity and acceleration to find displacement over time. Clear definitions and complete questions are necessary for accurate guidance. Understanding the underlying principles will enhance the effectiveness of the calculations.

What are some formulas that I should use to calculate this. Give some examples please.

We cannot read your mind, please make a complete statement of your question. What is R? In what sense are you using displacement?
 
i suggest differential calculus, Newton's laws and some common sense (whatever that means)
 
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...
