The probe splash-lands into a "liquid-tube" with a radius of 1.5 m. The fluid of density of 1.78 g/cm3 carries the probe through a 100.0 m mini-corridor and pops out at the other end that has a 2.0 m diameter opening. What is the final velocity of the probe at the end of the corridor? If the probe barely floats, what would be its volume? What type of fluid is this that the probe floats on?
