### How far can rioters throw?

Watching video footage of some of the riots, I started to wonder "How far can the average guy throw?"

It is not a simple question.

There are two populations:

The elite throwers played baseball, softball or played quarterback or threw the javelin in high school.

Then there was everybody else.

Everybody else
According to folks who watch the radar guns at baseball stadiums, Joe Average Public does well to throw a baseball at 45 miles per hour. It is a matter of mechanics and condition.

To obtain maximum distance, the release needs to be somewhere around 45 degrees. That will reduce the release velocity.

But for the sake of these approximations, let's go with 35 degree release and a 45 mph initial velocity.

According to this site, the best that thrower could hope to throw is about 125 feet with a "hang-time" of about 2.3 seconds. Since I have been dragging 100' hoses to water the garden, I can vouch that 125' is not very far.

It should be obvious that bricks are not easy to grip and are heavy. All bets are off on how far folks can chuck a brick, but it is not very far. We are talking about rocks that are approximately the weight of a hardball.

Elite throwers
We are talking about gifted athletes who trained to throw. These are the top-drawer, high school pitchers and college level outfielders. He is in the top 1/2%.

He can throw at 75 miles per hour, has a range of about 350 feet and a four second hang-time.

The guys who played Little League and is still in shape, he might be able to manage 60 miles per hour. He is in the top 5%.

That guy can throw 225 feet. This is the guy you have to watch out for. He can be standing 50 feet behind the average guy and bean you while the average guy's throws are still falling short.

And there are enough throwers like him to make it likely that any group that is larger than twenty will have one.
