11) A 98 N person is standing on a board, 1 m from the end. The board is balanced on a point that is 2m from the same end. The board is 49 N. How long is the board overall? mboardboard +mx. 1pxp XCM m board +mp 5xboard+10(-1) -2= 5+10 -30=-10+5xboard Xboard = -4m m=10kg mboard CM 1.0m 2.0m Xboard Setx=0 12) Describe three methods to find the center of mass of this L-shaped piece of cardboard. Draw diagrams to help your explanation. 13) Challenge question: Where is the center of mass of the object in the preceding question if the length of the sides of the squares is 1 m? Give numbers. 14) Challenge question: A honeybucket man is carrying his load. He has a pole 2 m long with a bucket hanging from each end. The buckets have a mass of 2 kg each. The pole has a mass of 1 kg. The front bucket has 5 kg of "honey" in it, and the rear bucket has 3 kg of "honey." from the center of the pole is the honeybucket man's shoulder?
