A stone is launched straight up by a slingshot. Its initial speed is 19.6 m/s and the stone is 1.50 m above the ground when launched. (a) How high above the ground does the stone rise? (b) How much time elapses before the stone hits the ground?

One type of slingshot can be made from a length of rope and aleather pocket for holding the stone. The stone can be thrown bywhirling it rapidly in a horizontal circle and releasing it at theright moment. Such a slingshot is used to throw a stone from theedge of a cliff, the point of release being 20.0 m above the baseof the cliff. The stone lands on the ground below the cliff at apoint X. The horizontal distance of point X from the base of thecliff (directly beneath the point of release) is thirty times theradius of the circle on which the stone is whirled. Determine theangular speed of the stone at the moment of release.
