(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A ball tied to the end of a string swings in a vertical arc under the influence of gravity. When the ball is at an angle of 23.5 degrees to the vertical, it has a tangential acceleration of magnitude gsin(theta). Calculate the angle between the total acceleration a and the string at theta 23.5.

2. Relevant equations

I first solved for the total acceleration using a = square root of [A(radial)^2 + A (tangential)^2]

3. The attempt at a solution

But then I don't know what to do next. Can someone please give me some hints? Thanks!
