a) Find the mass of the hanging weight, mp, required to balance the egg as it rotates. b) Find the centripetal force, Fc, on the egg. c) Find the angular velocity, w, of the egg. d) Find the tangential velocity, vt, of the egg. Assume the collector won't pay and I decide to destroy the egg by cutting the cable at the point marked "cable cutter" shown in diagram (b). e) Show on diagram (b) the path the egg takes when the cable is cut. f) Neglecting air resistance, show that energy is conserved once the egg is in free fall. You are a police inspector in the Art Theft Department. You find my arrangement for ransoming the egg and realize that if the apparatus is tampered with (the electricity is cut, for instance) the cable cutter engages and cuts the cable. Because you took PHYS 201N, you can calculate where the egg will land if the cable is cut. You also realize that by placing a piece of foam at the egg's landing spot you can cushion the impact enough to save the egg. Fortunately, you have a piece of memory foam in your car. g) Where do you need to place the foam in order to cushion the egg's landing? Calculate the distance the egg travels and mark the landing spot on diagram (b).
