## Homework Statement

Hi there. Where, I got this exercise. I have a ball attached to an ideal rope with longitude L, moving on a circle with speed V on a circular trajectory with radius R over an horizontal plane.

So it asks me to express the subjected force over the rope as a function of the parameters given on the image below.

So I thought of [tex]a_n=\dysplaystyle\frac{v^2}{R}[/tex], but the force given by this acceleration isn't the one I'm looking, right? I think I should use some trigonometry to find the projection of the force [tex]F=m*a_n[/tex] over the rope.

What you say?
