Solve Tetherball Problem: Find Rope Tension & Pole Force

[jnolan]

Hi. I know it is rude to have your first post be a question, but I am out of time for this (it is due in an hour), so if someone could help, it would be greatly appreciated.

A tether ball leans against the post to which it is attached (Fig. 5-40). If the string to which the ball is attached is 2.00 m long, the ball has a radius of 0.300 m, and the ball has a mass of 0.400 kg, what are the tension in the rope and the force the pole exerts on the ball? Neglect any friction between the ball and the pole. (The string is attached to the ball such that a line along the string passes through the center of the ball.)

Find the Tention in the Rope

Find the Force of pole on ball

UPDATE: I just got the first one. I was accidentally thinking that there were 2 ropes pulling it.
I have tried 4 times (its an online submition thing) and only have one more shot. Any help would be appreciated.

What I have tried so far:
To solve for the angle between the poll and ball:
Theta=ArcSin(.3/2.3)=7.43 degress

the rope is the only thing capable of applying a vertical force, so it must take care of gravity entirely. Then you need to figure out what the horizontal forces look like (given the angle, and the vertical force, it's basic triangle trigonometry)
