I almost hit someone in an adjoining fairway (almost several times, really), and I'm wondering how hard of a hit that would really be (and I'm a loud mouth and always yell fore at the top of my lungs -- some hear it, more don't).  In my case, figure on about a 300-yard tee shot, so usually about 280-290 in the air from a 110-115 swing speed, so 160-170 ball speed.  I've seen the balls land and they're nowhere near as hot as the ball is just after it is hit (that screaming duck hook can kill someone close for sure!).  6-7 seconds of flight time takes a lot off of that ball speed.  So what are we left with? 50mph? 75mph? 100mph?

Ok.
Velocity=distance/time
300 yard drive in the air for say 6 seconds. 50 yards per sec or 150 feet per sec.
150 feet per sec is 45.72 meters per sec.
Since the ball is not in a straight line and is falling down, subtract the force of gravity. (As the ball is following nature and is adding to its speed)
45.72 m/s - 9.8 m/s= 35.92 m/s
35.92 m/s is about 80 mph.
The ball should be landing at about 80 mph (enough to leave a mark :) )

V^2-Vo^2=2AS.
S=vt.
So, V^2-Vo^2=2A(vt).
And v=gt.
Solve for the height of the parabola, then for t based on g. Then you get v.
Then for bonus, solve for f=ma, and get how many newtons hit the skull...

I've taken a descending 300 yard drive from a fairway way below (50 feet or so) and sideways of the perp.   It was moving,  Sounded like a missile before impact, hitting my ribs with a loud thwack (think Rocky working the meat slabs).  Left a comet like streak with a big circular bruise, lasted a good 4-5 weeks

*assuming no air resistance*
a golf ball launches at 14* with ball speed of 180 mph will hit the ground @ roughly 93 mph

**considering air resistance**
golf ball will most likely reach its terminal velocity of 72 mph based on its mass and area

I figure something above terminal velocity for a golf ball depending on trajectory which is 72MPH.  If hit on a frozen rope for 300yds considerably higher.  If a high trajectory probably not much above terminal velocity.

"This velocity is known as Terminal Velocity and in the case of a golf ball with a radius of 2.1 cm, an area of 14cm² and a mass of 46 grams, this will be 32 meters per second or 72 mph."

http://www.golf-simu...com/physics.htm

So minimum of 72MPH.  It's gonna hurt.

Not only did I have the branding imprinted in my leg for three weeks, the skin on my quad broke and there was a slight recess where the ball just about impaled in it.

It was going fast enough to hurt like hell.

He never said “drive” or “driver” and only called it his Tee shot. Being that this is Golf WRX, I bet he hit 7 iron.

dimples will improves golf ball's drag coefficient and help golf ball to reach its terminal velocity faster, terminal velocity will not change as long as golf ball's mass and surface area doesn't change.

That terminal velocity is with no spin. Add spin and there is more drag (and lift) and the ball will slow down even more.   I've seen reports that for a 100 mph swing speed, 148 init ball speed, 11* driver - the ball speed when it hits the ground will be down to a bit less then 50 mph.

Not quite as bad but still enough to do some decent damage if it hits the 'wrong' spot.

I've seen three guys hit.  One literally walked under a pitch from maybe 10 yds, knocked him to his knees and left a ding on his head.  Another was hit by a 3 wood from about 240.  That ball caught the edge of the cart top, hit my friend just under the eye.  Knocked him over, left a big nasty mouse, and would have been way worse if the cart hadn't taken the brunt of the impact.  The third was exactly the same scenario the OP described.  A ball from another tee hit my friend squarely in the stomach.  Left one of those big bruises that has an ugly yellow center.

I have been hit once on  the shoulder while on the green of a par 3. Of more note a 27 year old just died in NZ a few days after being hit on the temple after standing to the right of one of his friends on the tee. Most unfortunate.

I was double-bagging it for my dad and his guest in a tournament long ago.  After putting out on the 17th green, I gave them their drivers and headed down the hole about 150 yards off the tee.  

I put the bags down and sat on the end of one.  Suddenly, a ball hit me just above the knee, luckily on my thigh muscle.

Neither my dad nor his friend were high caliber hitters, but I had a golf ball mark on my leg for a few days.

It was the 18th hole, so I was able to limp to the finish.

If that was going 50 mph, I wouldn't want to be hit by anything harder.

FWIW, I shoved some #'s into a piece of software called "trajectoware" (input CH speed, angles, loft, etc - the usual impact parameters). For a 300 yard drive for the impact conditions I chose (resulting carry of 300 yards), the initial BS was 183 mph and the final BS was 63 mph.

Hey - it was a 15 year old piece of software that I found somewhere - I cannot imagine how this could be wrong :-)

i was walking down a fairway, after playing a par 3 and teeing off on a par 4. Just as I left the tee box. I was hit in the bicep by a sliced 7 iron. It left a big bruise for about a month. You could see the dimples in the bruise.  And it hurt.    I wouldnt want to get hit by a driver.

This actually comports with my "educated guess" number.  I suspected it was slower than previous posts about terminal velocity based upon seeing the ball come down when hit by others within my vicinity, and thinking about known estimates of ball speeds in baseball, etc.

Terminal velocity is when the opposing aerodynamic force (drag) is equal to the force of gravity (for an object falling straight down). The ball is headed toward zero velocity horizontally (x direction) and toward its terminal velocity vertically (in the y direction). But it hits the ground before either of those happen. Like you, I don't think that thinking in terms of terminal velocity is particularly helpful here.

Ok.
Velocity=distance/time
300 yard drive in the air for say 6 seconds. 50 yards per sec or 150 feet per sec.
150 feet per sec is 45.72 meters per sec.
Since the ball is not in a straight line and is falling down, subtract the force of gravity. (As the ball is following nature and is adding to its speed)
45.72 m/s - 9.8 m/s= 35.92 m/s
35.92 m/s is about 80 mph.
The ball should be landing at about 80 mph (enough to leave a mark :) )
