Can it be possible to make a cannon like from Jules Vernes novel?
I would like to try that space mission for real

Yes, but surviving the shot would be the hard part.

That was quite a notion in Jules Vern"s day, even something proposed seriously by a few scientist.
May even be what sparked those human cannonballs at carnivals, some died doing that.
Just a few physics one would need to overcome.
First would be the acceleration impulse power to launch such projectile to escape velocity, the G forces would be massive( one can work the numbers) The rocket sleds of the 50s slowly accelerated at near 15 Gs, the limit a human can maintain consciousness, you are talking like 150,000 Gs. That would mash any biologic.
Now Jules Vern never did say how these people to the moon 'GOT BACK TO EARTH' so it would be a one way trip. Now to get a little more real hear.
The US navy has the most powerful 'cannon' on the planet. A 50 megawatt 'rail gun'. In a test, this gun shot a 7 pound projectile a distance just over 100 miles. the muzzle speed was 4800 MPH (mach 6+) or twice as fast as SR-71 blackbird, About as fast as the space shuttle reaching boundary on reentry, and we know how hot that got.
In theory, this rail gun 'might' be able to put a projectile into orbit for a while, but would not escape earths gravity.
With mans smarts, I suppose something like this is remotely possible, engineering a capsule that wouldn't burn up or disintegrate, a fluid atmosphere to take the G forces, a huge 'rail gun' design with tremendous power.
Just that there are far better methods for putting a human into space

NO, the capsule would have to speed up gradually, otherwise, the inertia would suddenly crush the occupants.

anyone trying that will be smeared into a monomolecular layer in the cabin if trying that

The Physics would be impossible

you would die instantly. you would be turned into goo

An early nuclear test inadvertantly did exaclty that. Operation Plumbbob, see the wiki entry below.
It was an underground test with the nuclear bomb down a very deep well, if you imagine the well acting like the barrel of a gun. They covered the top of the hole with what looked like a large manhole cover. When they shot the bomb off they had high speed cameras running that were capturing 1000s of frames a second. Well, the manhole cover is in the air in one frame and not in the next. A little bit of math and they determined it was possible (if it didnt get vaporized) to have been going upwards of 250,000 miles an hour. The ISS by comparison is abotu 19,000.
If true, the manhole cover was the first object (a few months before sputniK) in orbit and remains the fastest object ever created by man. It was more than fast enough to reach escape velocity.

a linear accelerator (aka mass driver) is one possibility.
A mass driver or electromagnetic catapult is a proposed method of non-rocket spacelaunch which would use a linear motor to accelerate and catapult payloads up to high speeds. All existing and contemplated mass drivers use coils of wire energized by electricity to make electromagnets. Sequential firing of a row of electromagnets accelerates the payload along a path. After leaving the path, the payload continues to move due to momentum.
Although any device used to propel a ballistic payload is technically a mass driver, in this context a mass driver is essentially a coilgun that magnetically accelerates a package consisting of a magnetizable holder containing a payload. Once the payload has been accelerated, the two separate, and the holder is slowed and recycled for another payload.
Mass drivers can be used to propel spacecraft in three different ways: A large, ground-based mass driver could be used to launch spacecraft away from Earth, the Moon, or another body. A small mass driver could be on board a spacecraft, flinging pieces of material into space to propel itself. Another variation would have a massive facility on a moon or asteroid send projectiles to assist a distant craft.Source(s): https://en.wikipedia.org/wiki/Mass_driver
