## Homework Statement

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?

## Homework Equations

trig, f=ma, some circular one

## The Attempt at a Solution

a) 360N

b) =131.029N

c) 338.289N

d) ok this is the one I am stuck on at the moment

I'm thinking that i need to use this equation

*a=(v^2)/(r)*but i don't have a clue what r is nor how to get it (which is question e)

thanks for any advice or help
