a small ball of mass 38g is suspended from a string a length 59cm, and whirled in a circle lying in the horizontal plane. The acceleration of gravity is 9.8m/s2. if the string makes an angle of 31o with the vertical, find the centripetal froce experienced by the ball. here's the diagram:(the best i can do) it looks like a triangle when i view it but then it goes all weird in the actual view. sorry. l\ l \ l \ 59cm l \ l \ l O=38g then there's the dotted lined circle drawn, but i don't know how to do that here. ok, so first i found the radius using trig and got it to be 30.3872m. then i was going to find velocity, but then i don't know how to do that. help would be greatly appreciated. thanks sooo much.
