    Friction Homework
AI Thread Summary
The discussion revolves around calculating the acceleration of a larger block influenced by friction coefficients with a smaller block and the ground. Participants emphasize the importance of understanding the forces at play and suggest creating a larger diagram for clarity. There is a focus on drawing a free body diagram (FBD) to visualize the forces involved. Caution is advised as several forces may be easily overlooked in the problem. Overall, the thread highlights the need for careful analysis and visualization in solving the physics problem.

1. Homework Statement :
friction.png
In the diagram,the coefficient of friction between the bigger block and the smaller block is μ1 and the coefficient of friction between the bigger block and the ground is μ2. Calculate the acceleration of the bigger block.(As seen in the diagram,M is the mass of the bigger block while m is the mass of the smaller block.




2. Homework Equations : F = ma



3. The Attempt at a Solution : I have absolutely no idea about the question,so I need help.

Can you make a bigger diagram? It's very difficult to look at it

Just right-click on the diagram and select "Open in new tab". That'll do the trick.
 
Usually, the first thing to do in such cases, is to draw all the forces involved. Can you do that?

Yeah,I know how to draw a FBD.
 
Better get started then ;)
Just be careful, there are several forces in this problem that I would think are very easy to forget about ...
 
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...
