Mechanics (Non-inertial systems and Fictitious Forces)

AI Thread Summary
A sled slides down a slope with inclination α, and a man on the sled uses a spring balance to weigh an object with mass m. The key point is that the object shares the same acceleration as the sled, which affects the reading on the balance. The discussion emphasizes that air resistance is not considered in this scenario. The balance will indicate a weight that reflects the combined effects of gravity and the sled's acceleration. Understanding these dynamics is crucial for solving the problem accurately.

Homework Statement


A sled slides from a slope with inclination α. A man standing on the sled ‘weighs’ an object with mass m using a spring balance. What weight does the balance indicate?

I seem to be making it too complex, could anyone help me out with it?

The object has an acceleration which is the same as the sled's (and the same direction). I suspect we are not counting air resistance.

Yes that's correct I'm not counting air resistance!
 

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...
