Dinger Exit Velocity

[Lancer_dad]

I know that a lot of factors like launch angle play into It, but in general/WAG terms, what kind of exit velo should you be looking for, to clear a 5’ fence at 200’-230’?

70+

Batted Ball Distance:
Is calculated using Exit Speed and an assumed launch angle of 25° (line drive). Accounts for the effects of air drag, ball spin, and wind. Every 1 MPH on a well hit line drive will give the ball an added 3.3 feet in distance (4.5 feet for baseball)

200 to 230 is a big difference. 67.5 mph

That means a ball going 60.6 MPH with a launch angle of 25 degrees will go 200 feet, assuming ideal conditions. That seems a little slow on the exit velocity to hit the ball that far.

I wonder if I can test that theory with a Jugs machine, or would the dimpled balls disrupt the flight path too much?

68mph at 31deg will net you 201ft. Will need 75 for 230ft.
Add a little extra to carry the fence depending on height, wind, spin, etc etc etc.

No idea on the math but off the tee and off front toss dd is 64-68 and hits a reasonable amount of homeruns for a smaller kid 12 in her hs season 6-9 for a summer or fall season of 6-8 tournaments. She’s definitely not a power hitter. If you factor in that exit velo is probably higher off a faster pitcher I guess she’s probably over 70.

I was surprised spin can make a huge difference. At 68 and 31 I get 203’ with no lift. 238’ with lift from back spin.
I get 63mph at 31 degrees I get 5’ at 200’ using a 1.5 lift coefficient.
That maybe to generous. I did replicate 3-3.5 feet per mph at 25 degrees.

When Coach Lisle coached at South Carolina he made a statement like “at 26* launch angle and an exit velo of (64?) the ball would be out of most parks they played in.” It was a fairly low exit velo.

I wrote down the 26* number because at the time we were working on launch angle consistency. Long story, had good reasons to do that, wasn’t because of some twitter post.

Pitch speed does not contribute to higher ev. Urban legend.
