AI Thread Summary
The discussion revolves around calculating the acceleration of a coin dropped from a downward-moving lift, which accelerates at 1.5 m/s². The participant initially calculated the coin's acceleration as 11.5 m/s² but expressed doubts about this figure. Key points include the need to consider the forces acting on the coin after it is dropped, specifically gravity and the lift's downward acceleration. The net acceleration of the coin, as observed from the ground, would be the sum of gravitational acceleration (approximately 9.81 m/s²) and the lift's acceleration. Ultimately, the correct approach to the problem requires a clear understanding of the forces involved.

What causes acceleration?

What causes acceleration
A force applied to an object at rest causes it to accelerate in the direction of the force.

And what force(s) act on the coin after it is dropped?
 

Thread 'Rolling without slipping on a curved surface'

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 .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

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...
