Acceleration can be determined from a velocity vs. time graph by calculating the slope of the graph. Conversely, velocity is found by determining the slope of a displacement vs. time graph. Understanding these relationships is crucial for analyzing motion in physics. Proper interpretation of these graphs allows for accurate calculations of both velocity and acceleration. Mastering these concepts is essential for solving related physics problems effectively.

Homework Statement
I just want to know how you determine the acceleration on a velocity vs. time graph and how to determine the velocity on a displacement vs. time graph.
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...
