This is a normal post going the other way
would it just get stuck in the barrel? or travel at 120mph? I'm assuming the first?

This is a normal post The second one.
Remember that the cannonball is already moving at 60mph before the powder goes off.

This is a normal post so if you were travelling at the speed of light
would it go at the speed of light +60mph then?

This is a normal post well no
that's against to laws of physics, nothing exceeds the speed of light

Physics stops it happening for some reason. Everything slows down the closer it gets. I don't know this to be true though but this is what people say. I don't understand the maths but I trust them this is correct. A bit like the Bible

This is a normal post That is not strictly true.
It is only so because that is how we measure it. We use light to measure time and distance. So for us, time stands still if we reach the speed of light. But we know distance does not, because light has a finite speed and so you will not be everywhere at once.

So we know time and speed bring us to some happy sums that work out. But only if we measure in light speed. Add distance, and the sums get a little shakey.

Do you know, I never get invited to dinner parties?

This is a normal post correct
but why?

This is a normal post Because
nothing, that has mass, can travel at the speed of light

This is a normal post What about photons then, they have mass AND can travel at the speed of light.

This is a normal post they have zero rest mass
