Homework Statement
I whirl a 'tennis ball on a string' above my head (horizontally) with a period of 0.75 seconds. The ball has a mass of 150 g and the circular motion has a radius of 0.95 m. What is the downward angle of the string from the horizontal, the tension in the string, and the string length?
Homework Equations
Fc = 4π2mRf2
The Attempt at a Solution
Okay, I tried for very long to get to the answers .. with no success.
I think I am having trouble getting the situation set up.
I tried using like a banked curve situation to split into vertical and horizontal..
I think I can get Fc, but I am stuck after that :(
Please help!
