Question Title A superhero is designing a new rope-like gadget that will allow him to swing from building to building. The gadget is designed so that the rope is just strong enough to hold the superhero’s weight when he hangs on it (without swinging). The superhero decides that the gadget is safe and tries swinging on the rope Question Title The Scenario The design: The test: F T, max FgFg Superhero Side view Superhero v r

Question Title Consider the superhero when he is hanging onto the rope at rest. Which of the following is the correct free-body diagram of the superhero? Question Title Superhero Physics I FTFT FgFg A. FTFT FgFg B. FTFT FgFg C. FTFT D. FgFg E. Side view Superhero r F T = tension force F g = gravitational force

Question Title Consider the superhero at the lowest point of the swing. Assume the rope is r meters long and the superhero is moving at speed v. What is the direction of the net force on the superhero at this moment? Question Title Superhero Physics II v r Side view A.No net force B. C. D. E. F F F F

Question Title Which of the following is the correct free-body diagram of the superhero? Question Title Superhero Physics III v r F T = tension force F g = gravitational force F C = centripetal force FTFT FgFg A. FTFT FgFg C. FCFC B. FgFg FTFT E. FgFg FTFT FCFC FTFT FgFg D. FCFC Side view

Question Title A.The superhero swings safely across B.The rope breaks during the swing C.Cannot be determined A superhero is designing a new rope-like gadget that will allow him to swing from building to building. The gadget is designed so that the rope is just strong enough to hold the superhero’s weight when he hangs on it. The superhero decides that the gadget is safe and tries swinging on the rope. Is the superhero able to swing safely across? Question Title Superhero Physics IV The design: The test: F T, max FgFg Superhero Side view Superhero v r
