SUMMARY
The discussion centers on calculating the recoil speed of a submarine after firing a torpedo. The submarine has a mass of 2.3 x 106 kg, and the torpedo weighs 260 kg with an initial speed of 100.9 m/s. Using the conservation of momentum principle, the recoil speed of the submarine is calculated as Vsub = (260 kg * 100.9 m/s) / (2.3 x 106 kg), resulting in a recoil speed of 0.0114 m/s. The user notes that the online homework system requires more decimal precision for the answer to be accepted.
