Object dropped on trampoline - Acceleration

AI Thread Summary
When an object is dropped onto a trampoline, it causes the trampoline to expand upon impact. The discussion centers on whether the acceleration becomes negative after the trampoline expands. It is suggested that the acceleration should be considered negative due to the downward direction of the object's motion. The need for showing effort in problem-solving is emphasized, indicating that participants should engage more deeply with the physics concepts involved. Understanding the dynamics of the trampoline's expansion and the object's motion is crucial for accurately determining acceleration.

Well, I think that if the trampoline expands, the acceleration should be negative because your direction is negative.
 
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...
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 .
