A 10 kg dinosaur sign is to be hung from a long thin rod. The rod is attached to the wall by a hinge at point P and has a cable at the far end attached to the wall at a height h above P. The rod is 10.0 m long and held horizontal by the cable that makes an angle with the rod of 53 degrees. It also has a mass of 4.0 kg. a) How far along the rod should the sign be fastened such that the tension in the cable is to be 125 N (relative to the wall)? b) If the cable was accidentally cut what would the angular momentum of the system be when the rod was 30 degrees below the horizontal before smashing into Caroline's Dino-Store window (model the sign as a particle)? h P Caroline's Dino-Store
