AI Thread Summary
To determine how far the cat is from the right end of the plank when it begins to tip, one must analyze the forces and moments acting on the plank. The plank has a mass of 7 kg and is 4 meters long, supported by sawhorses positioned at 0.45 meters from the left end and 1.5 meters from the right end. As the cat, weighing 3.9 kg, moves from the left end toward the right, the tipping point occurs when the moments about the right sawhorse become unbalanced. The calculations involve setting up equations based on the weight distribution and the distances from the pivot point. Ultimately, the solution will yield the exact distance from the right end at which the plank tips.

1. Given a wooden plank mass 7 kg total length 4m supported by 2 sawhorses which are located l1=0.45m from left end and l2=1.5m from right end ...a cat with mass 3.9kg jumps on left end of plank and walks along to right side . How far is it from the right when plank begins to tip ?

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...
