You plan to throw stones by using a sling that you whirl over your head. You will whirl the stone in a horizontal circle with a radius of 1.50 m at a height of 2.50 m above the ground. If you want the stone to hit a target on the ground a distance of 15.9 m in front of you and 1.50 m to the side (note that this number is the same as the radius of the circle), what must be the magnitude of the centripetal acceleration of the stone just before you release it
