Homework Help Overview

The discussion revolves around a physics problem involving tension in a rope as a girl swings on a maypole. The scenario includes parameters such as the girl's mass, her speed, and the angle of the rope with the vertical, leading to questions about the components of tension and net forces acting on her.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss the vertical and horizontal components of tension, with some questioning the relationship between tension and gravitational force. There are attempts to clarify how to split tension into its components, and participants express uncertainty about the values needed for calculations.

Discussion Status

The discussion is ongoing, with participants exploring different interpretations of the problem. Some have provided partial guidance on the components of tension, while others express confusion and seek further clarification on how to approach the remaining parts of the problem.

Contextual Notes

Participants note the lack of complete information for solving parts B-E of the problem, highlighting the need for additional details or assumptions to proceed.

Physics Tension Question, Need urgent help

A Girl is swinging on a maypole in a playground. The Girl has a mass of 36Kg and, when she is moving with speed of 2.0m/s, the light rope makes an angle of 20 Degrees with the vertical. Consider the motion of the center of mass of the girl, which movies in a circle of radius r


A) What is the vertical Component of the Tension in the Rope?

B)What is the horizontal component of the tension in the Rope?

C)What is the tension in the rope?

D) What is the net force acting on the girl?

E)What is the radius of the circle?

Any Help would be Very Helpful. I did Part A with T=mg and got the correct answer of 360N, but i am stuck with B-E.

The vertical component is mg, not T=mg.

The horizontal component is Tcosθ. What is the value of T?

i don't know it doesn't have it, what i wrote down is all the information that we know

When you split the tension into two components, what are they?

Ty=?
Tx= ?
