Since angular momentum is conserved, if the moment of inertia decreases, then the angular speed must increase (L=Iw) If the ball is initially moving at 2.8 m/s in a circle with a radius of 0.30 m, what will be its tangential speed if the string is pulled down to reduce the radius of the circle to 0.15 m? ................
