One type of slingshot can be made from a length of rope and a leather pocket for holding the stone. the stone can be thrown by whirling it rapidly in a horizontal circle and releasing it at the right moment. such a slingshot is used to throw a stone from the edge of a cliff, the point of release being 23.2 m above the base of the cliff. the stone lands on the ground below the cliff at a point x. the horizontal distance of point x from the base of the cliff (directly beneath the point of release) is 29.0 times the radius of the circle on which the stone is whirled. determine the angular speed of the stone at the moment of release.

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
