Transcribed Image Text:

A 1.2 m³ block aluminum (density 2700 kg/m³) is lowered at a constant rate into seawater (density 1025 kg/m³) by a cable attached to a ship. A) What is the tension in the cable before the block hits the water? B) What is the tension while the block is lowered at a constant rate in the seawater? C) Later the block is pulled back up by the cable. What is the tension in the cable if the block is pulled up with an acceleration of 3 m/s²? (Neglect resistance from the water) A 1.2 m³ block aluminum (density 2700 kg/m³) is lowered at a constant rate into seawater (density 1025 kg/m³) by a cable attached to a ship.
