Question

A metal boat with ​M​ = 400 kg and dimensions 2 m x 1 m x 0.5 m (yes, it’s very poorly designed) has two captains (68 kg each) standing in it. A crack in the bottom of the boat leads to 4 L of water per second pouring into the boat. Assuming the captains can bail 1 L/s of water each, how many seconds after the leak starts does the water hit a level where even if the leak is patched the boat will still sink? As always, state any approximations you are doing.
