Assuming you have the proper research, would it be possible to create a land/sea vehicle that could break the sound barrier? Since we humans have already created jets that break it, shouldn`t it be possible to do this with other vehicle types.

In theory, I'd assume so once that particular point is reached. But getting something airborne to break the sound barrier is much easier than getting something on land or on the water to do so. So while perhaps a prestige project could be done, there might not be much practicality in making a supersonic land vehicle unit or a similarly speedy sub or battleship. It'd be cool, but also could be harder to make practical in terms of fuel costs.
Plus there's drag and atmospheric density modeling to consider, it's entirely possible for planets with different atmospheric densities to exist, so the speeds required to break the sound barrier can fluctuate. Definitely something for the programmers and coders to consider down the road though.

It's certainly possible for land and sea vehicles to surpass the speed of sound through air; the question is, could a seaborne vehicle surpass the speed of sound through water? I'm not going to say no, but I'm pretty sure the physics of that are very intense. You definitely have to use rockets or jet engines (and in the case of jet engines you can't submerge), and you need to have a shape that will prevent catastrophic water-hammer due to cavitation behind the shock wave. Much harder than an air or land vehicle, since land is generally hard enough not to be fractured too badly by any shockwave (well, it has to be for you to be able to drive on it ) and air is already solved.
