A woman stands on a horizontal platform that is rotating at a constant angular velocity
. If she is holding a cup of tea, and the center of the cup is 0.9 m from the axis of rotation, determine
 if the slope angle of the liquid’s surface is 5°. Neglect the size of the cup.

Determine the maximum height d the glass can be filled with water so that no water spills out when the glass is rotating at 15 rad/s.
