I was just making a we're/where/wear pun along with the fact "wear" isn't included in the picture above
I'm not sure at most 8 murders a year (I assume across the entire US but it doesn't say) would be described as all that common really

(Also just fyi imgur has its own meme generator that does this for you http://imgur.com/memegen )
The mass of the ball is irrelevant also, this experiment would work with a 5kg or a 500kg ball, just one would need more force for 50mph
You are saying the momentum of the truck is equal to the momentum of the cannonball? I'd imagine the truck probably weighs more and same v?
Obviously anything with velocity and mass has momentum, in this case it is simpler to understand just using velocities.
I was slightly concerned what was going to happen given the "ifyouarebraveeough" tag
Obviously the balls momentum changes as a result of its change in velocity, but you can just add the velocity vectors (50 + -50) for 0 mph
If you fire a ball of mass 5kg or of mass 500kg out of the back of the truck at 50mph what would change? Does the mass really matter?
All velocities are proportional to momentum as p=mv, you don't need to use momentum to make sense of the gif though, just add velocities
just about velocities - regardless of the mass any ball that has 50mph forward velocity + 50mph backward will drop
It would require more force to accelerate a ball of greater mass to the same velocity but the original gif speaks nothing about forces (1/2)
as opposed to forward firing where the missile already is moving at 1200 mph in the direction it is being fired
The missile is going 1200 mph in the opposite direction to the firing, so the velocity change is 1200 mph + whatever it needs firing at (1/2

Shame, I haven't watched all of the later seasons but first few seasons they really just didn't give a fuck who they killed off.
Except Game of Thrones (not a movie I know but the same principle applies to most TV shows also)
Not bad at all, did you follow these instructions?
I tend to view the first 10 images unless it's really top notch or not that much longer, if it's 250 pics
