    Friction Tension
AI Thread Summary
The discussion centers around a challenging physics problem related to friction and tension that students struggled to solve during a quiz. The key equations mentioned include net force equals mass times acceleration and acceleration as velocity squared over distance. The student attempted to use free body diagrams and algebra but found no progress. They also noted that the problem attachment was inaccessible due to pending approval. The conversation highlights the need for collaborative problem-solving and resource sharing in tackling complex physics concepts.

Homework Statement


The problem enclosed was given as a one problem quiz by my physics teacher. Out of both Honors classes, nobody got it, so he sent it home. I still have little to no idea on how to solve it.

Homework Equations


net force=mass*acceleration
ac=(V^2)/d

The Attempt at a Solution


I drew the free body diagrams and tried to do some algebraic maneuvering but none of it got me anywhere. HELP...please

he said we could use any resources that we found
 
The attachment is unaccessible by me... It says pending approval.
 
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 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
Thread 'A bead-mass oscillatory system problem'
I can't figure out how to find the velocity of the particle at 37 degrees. Basically the bead moves with velocity towards right let's call it v1. The particle moves with some velocity v2. In frame of the bead, the particle is performing circular motion. So v of particle wrt bead would be perpendicular to the string. But how would I find the velocity of particle in ground frame? I tried using vectors to figure it out and the angle is coming out to be extremely long. One equation is by work...
