Block A is released from rest at the center of a tank of water. The block accelerates upward. 1. At the instant the block is released, is the magnitude of the buoyant force on block A greater than, less than, or equal to the magnitude of its weight? Explain your reasoning. 2. When block A reaches the surface, it is observed to float at rest as shown in the diagram on the right. In this final position, is the buoyant force on block A greater than, less than, or equal to its weight? Explain your reasoning. 3. If 90% of block A lies below the surface of the water in its final position, then what is the density of block A? Explain/show your reasoning. A Final position of block A Imagine that block A were released in the center of a tank filled with a fluid that is twice as dense as water. 4. Describe what will happen to block A after it is released. 5. Calculate the percentage of block A that is submerged after block A comes to rest . Explain/show your reasoning..
