Ball Clay Impulse Rubber Wall

AI Thread Summary

The discussion revolves around the impulse exerted by a rubber ball and a clay ball when thrown at a wall with the same initial velocity. The rubber ball bounces back, while the clay ball sticks to the wall, resulting in different momentum changes. The impulse is defined as the change in momentum, which is greater for the rubber ball due to its rebound. Since the clay ball's momentum after the collision is zero, it exerts less impulse compared to the rubber ball. Therefore, the rubber ball exerts a larger impulse on the wall.

is it the ball bouncing back? since the momentum of the clay ball after collision is 0

Indeed.

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 'I've come across another fluid pressure problem I don't understand'

Neglect gravity other than that of water; neglect friction. F1=ρgsh=1000*10*1*(1+4)=50000 N; F1=ρgsh=1000*10*0.1*4=4000 N; F3=50000-4000=46000 N?

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...
