Total Acceleration of a Ball Whirled in Inclined Vertical Circle

[cfkorea]

hmm.. I have a question.

If a ball is whirled in a vertical circle inclined from the horizontal axis

at angle $$\theta$$. what is the total acceleration of the ball?

Show your works. You have to use a free body diagram here. Just find it with respect to theta and the angle phi that it makes with a fixed diameter in the circular path drawn by it.
