AI Thread Summary

The discussion revolves around a physics problem involving a collision between two railroad cars, one moving and the other stationary. The key concept to apply is the conservation of momentum, which is essential for solving inelastic collision problems. The initial momentum of the system can be calculated using the mass and velocity of the moving car, while the final momentum includes the velocities of both cars post-collision. Participants encourage using this principle to find the speed of the empty car after the collision. Understanding momentum conservation is crucial for solving similar physics problems effectively.

Hi GunarsA

Welcome to PF !

did you try Using conservation of momentum??

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...

Thread 'How to find eddy current (circular) path in this pendulum experiment?'

Does the direction my second finger points in indicate the literal direction of magnetic field at that point in space, or do I need to further use right hand rule or something for a circular path around the finger
