I’m working on a physics question and need support to help me study.
supposed enriched uranium contains 3.4%of fissionable isotopes is used for fuel of a ship. the water exerts an average frictional drag of 1.010 5 N on the ship. Assuming that the energy released per fission reaction is 200meV and the ships engine has an efficiency of 20%; find how far the ship can travel per kilogram of fuel. the ships engine must supply enough energy to overcome the drag force.
U-235 has a molar mass of 235g/mole. the number of moles in 1kg of uranium is 0.145 moles.
