A new idea for public transit

[Petrolheadia]

They can shut down one cannon but not the rider.

It wouldn't be slow. 40 seconds to go say 400-500m.

Not really.

As far as security goes, arm the rider with grenades to drop onto oncoming attackers in transit.
And for my part, speed is secondary as to how interesting the ride is.
And having grenades would make the ride very, very interesting.

Well, exploding on landing is something interesting.

Comprehensive grenade handling tutorials are short and sweet, and can be given professionally and concisely as people wait in line.

They would still explode after having the forces of the landing applied.

No they wouldn't; sheer force doesn't explode explosives. Fire does. Force doesn't generate fire.

I will jump on a trampoline with grenades on my belt if you like, pins unpulled.
I promise I will not explode.
Or did you miss the part where passengers land in nets.

Now drop a five ton weight on me after I land, and maybe something besides me will pop.
Maybe.

Ok, I thought of a new way of public transit thats

1.Free to ride
2.Is impervious to terrorist attacks
3.Green
4.Awesome
5.Is safer then driving a car

I did this in my NS nation and most people thought it was a good idea.

The idea is:

Big air powered cannons that will blast you from place to place via cannons and safety nets. Safety nets get replaced daily.

What do you guys think about this actually being a real world?

RIP all those foolish humans who thought this idea would work...

Clowns are already terrorizing civilians. We don't need them influencing our infrastructure as well.

I much prefer the space under my bed to the corner.

It is a fantastic idea except for one thing.
Real people are not as resilient as video game characters.
Professional stuntmen do that sort of thing for a living IRL, and the wear and tear is considerable.
A+ for out of the box thinking though.

Also the fact that real human cannons, even with trained stunt men have a VERY short range and of course very low rate of fire. And can fire only one person at a time. It would be much faster, easier and safer to walk. Waiting in line to get shot half a block is not efficient.

Depends on the type of explosive. And impact fuses are a thing.

Sometimes I carry around an armed 155mm shell with an impact fuse. Especially when I am going to be shot from a cannon. Beacause why not?

[Novus America]

This is wrong on so many levels.

First, firing with a non-hurting force would fire a person for a few meters at best, which means we would need hundreds of cannons to cover a mile.

Second, it would be incredibly inefficient, as 1 cannon can only take 1 human, while a car can take 5 and a bus can take 50.

Third, getting yourself prepared for the launch would take over a minute.

Fourth, it's hard to get off a net soft enough without constantly falling over on it.

Fifth, terrorists can attack cannons, can't they?

So we would end up with expensive, slow (ca. 0.1 mph
of average speed) system. Anything is better.

They can shut down one cannon but not the rider.

It wouldn't be slow. 40 seconds to go say 400-500m.

Not really.

You cannot fire a human cannon 400m. Well without the person dying. You might want to review your physics.

No, we are just pointing out, that, unbelievably, grenades are meant to explode when a big enough force is applied.

[Risottia]

You should really quit listening to LG.

Seriously: do you have any idea of the acceleration needed to reach a muzzle speed enough for the mishap to travel a significant distance?

LG?

Insurance companies would never insure such an idea. Nor would municipalities give out a license. Which means the best form of public transportation compared to Cannon travel is - (see video)

Yes we do. We definitely do.

Ok, now enough goofiness and let's do some maths.

Our OP says "40 sec to travel 400 m". Let's ignore, for the sake of simplicity, the friction with air (we could assume the passenger is placed in a lightweight aerodynamic casing).

That means a horizontal speed of 10 m/s.

Let's reckon the initial vertical speed. v_0y=g*t/2 where g is the gravitational field near the Earth surface (g=9.8 m/s²) and t is the flight time.

This yields v_0y= 9.8 * 40 / 2 m/s = 196 m/s

By Pythagoras' theorem, the total velocity at the muzzle is [(196 m/s)²+(10 m/s)²]^0.5 = 196.25 m/s .

Now let's assume a fairly standard cannon. How about a 10 m long barrel? That's about the size of a battleship gun.

In 10 m, our commuter needs to be propelled from 0 to 196.25 m/s. a = v²/(2*s) where a is the acceleration and s is the displacement.

Unless I'm much mistaken, we're talking 1925.8 m/s², that is about 200 g.

SPLAT! Dead before even leaving the barrel.

And remember, we left out the friction with air.

Ok.

This involves significant trauma to your body, even if you use a net, if consistently used.
