Calculate Average Acceleration of Non-Uniform Cylinder Down Inclined Plane

AI Thread Summary
To calculate the average acceleration of a non-uniform cylinder down an inclined plane, the equation d=vt+0.5at^2 is suggested, but its applicability is questioned due to the need for known distance and initial velocity. It is noted that the cylinder's acceleration changes based on the incline angle, with full acceleration at 90 degrees and none at 0 degrees. The discussion emphasizes the importance of understanding how incline affects acceleration compared to free fall. Clarification on the specific parameters needed for accurate calculations is sought. Overall, the conversation revolves around the complexities of applying basic kinematic equations to non-uniform motion on an incline.

Homework Statement


Calculate the average acceleration of a non-uniform cylinder (large can of tomato soup) down an inclined plane.


Homework Equations


What equation should I use?


The Attempt at a Solution


I think the equation I should use is d=vt+0.5at^2, but I am not sure. If I use that equation, is there anything I have to assume?

I don't think you can use that equation. You'd have to know the distance and the initial velocity. Well, really, you could assume the distance to be anything and velocity to be 0 at start, but you'd have to know how long it took you to travel that distance.

So no, it won't work.

Is that honestly the entire question? If it is, then I can help a bit. What is the normal acceleration of just dropping something? Now, when you put it on an incline, it slows down, right? As in, it will still go down, but not as fast.

And if you put it on a flat surface, it won't fall at all. Okay, so at 90º it's full acceleration, and at 0º it's 0. Do you know of any function that works like that?
 
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...
