2. Our strategy is that to make sure that the blocks that we are using to have a centre of mass before the edge of the table. Since we need the blocks to extend far out of the edge of the table, we need to have a strong base which has most of the mass of the blocks concentrated at the bottom, because by the law of gravity, the lower the centre of gravity (centre of mass) is, the more stable the object is. Also, if we want to extend as far out as we want, we have to make sure that the distance of the blocks from each of the previous ones (that is over the edge of the table) have to add up to be not more than the distance of the blocks that are before the edge of the table. This is so as to make the tower as stable enough so as not to topple. 3. Let n be the number of blocks that we are going to stack up. Length of each block = 26 cm Let the distance that the first block could extend as far out from the edge of the table to be 1 unit. n = 2, the distance is ½
