Homework Help Overview

The discussion revolves around the dynamics of a conical pendulum, specifically how a mass suspended from a string maintains constant velocity while revolving in a horizontal circle. Participants are exploring the forces and motion involved in this system.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants are questioning the forces acting on the object and the nature of the momentum vector throughout its circular motion. There is a request for hints to initiate problem-solving efforts.

Discussion Status

The discussion is in an exploratory phase, with participants seeking clarification on fundamental concepts and expressing a need for guidance to begin their analysis. No consensus has been reached yet.

Contextual Notes

One participant has indicated a requirement for hints before proceeding, suggesting that there may be constraints on the level of assistance they can receive without demonstrating prior effort.

A small object of mass(m) is suspended from a string of length (L). The object revolves with constant speed (v) in a horizontal circle of radius (r),(Because the sring sweeps out the surface of a cone, the system is known as a conical pendulum).Find that the expression for V (speed) is :

v= square root of (L g sin(theta) tan (theta)

What do you need help with? Where are you stuck? We can not help unless you first show us what effort you have made.
 
I need a hint to start!
 
What are the forces acting on the object? What is the momentum vector of the object at any point in the circle?
