A particle is released on the smooth inside wall of a cylindrical tank at A with a velocity v which makes an angle beta with the horizontal tangent. When the particle reaches a point B a distance h below A, determine the expression for the angle theta made by its velocity with the horizontal tangent at B. There is a constant radius r along this path.

I have no idea where to begin. Do you have to put this in cylindrical coordinates? If so how do you go about doing that?
