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?

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

T_y=?
T_x= ?
