Question

Particle $A$ and $C$ are situated at a vertical distance $h$ apart which is a constant distance between $A$ and $C$ always. A has a velocity $u = 15 m / s$ at an angle of $60^{o}$ with horizontal and $C$ has a velocity $V$ at an angle of $30^{o}$ with horizontal. The angular velocity of $C$ relative to $A$ is $2 r a d / s e c .$ Find $h .$
