A grappling hook, attached to a 1.5-m rope, is whirled in acircle that lies in the vertical plane. The lowest point on thiscircle is at the ground level. The hook is whired at a constantrate of three revolutions per second. In the absence of airresistance, to what maximum height can the hook be cast?
