One kind of slingshot can be formed from a length of rope and a leather pocket for holding the stone. The stone can be thrown by whirling it quickly in a horizontal circle and releasing it at the right moment. Such a slingshot is employed to throw a stone from the edge of the cliff, the point of release being 26.0 m above the base of cliff. The stone lands on the ground beneath the cliff at a point X. The horizontal distance of point X from the base of cliff (directly below the point of release) is 30 times the radius of the circle on which the stone is whirled. Find out the angular speed of the stone at the moment of release.
