Thanks in advance for any help. I used the counter on a video editor to measure the time from the spike to when Payton was struck. The counter says .06 seconds. That seems to short to me. Anyway...at .06 travel time, if my math is right, figures to 142mph. Way too fast. I think I'm off by 50%. 70mph seems more likely. Any help is appreciated.

The Average Speed of a Volleyball Spike From Men

By John Shea, 09 July, 2013

Olympic Games
The average speed of a volleyball spike from men is most impressive at the Olympic beach or indoor level. Bulgaria’s Matey Kaziyski, for example, recorded a spike that reached 132 km/h, which is equivalent to 80.8 mph, in an international volleyball match in 2012. The average speed of an Olympic volleyball spike from men is roughly 70 to 80 mph. The velocity is highest at this level since the attackers have the necessary mechanics to pummel the ball.

Collegiate Competition

The men's game at the college level doesn't draw the same attention as that other indoor sport, basketball, but it's still a showcase for guys who can throw it down. The average speed of a man’s spike in NCAA competition is charted in the 50 to 60 mph range.

Spike is from center of court and she is at the side foul line. So if she were standing on the front line that’s 3 M from the net but it’s also 1/2 the width of the court.. which is 15’ or so.. so that makes the distance from where ball was struck to where she is on that diagonal somewhere around

The square root of (9+25) meters.. which is about 5.83 meters.

But the ball also had to travel a vertical distance from where it was hit to the height of her head. So would need to calculate that hypotenuse of that triangle and add it to the 5.83M. And then you have roughly how far the ball traveled in that time.

The ball wasn’t going 143 MPH, fastest spikes by pro men players are in the 100 mph range so no way this sicko hit a 145mph

Nevermind wasn’t center court. But still no way it’s near 145mph

Spike is from center of court...

Not from center...they are both almost equal distance from the FL. Gotta look close...sorry the image insnt clearer. I think im pretty close on the distance numbers. The time is whats wrong..I think. I need a better timer.

A really good major league fastball is 100 mph

A really hard NHL slap shot is 100 mph

So I doubt it’s faster than that

Video frame rate is key. 30 fps, frames per second.

Time interval = 6 frames / 30 frames per second = 0.2 seconds

Distance traveled = 3.65 meters

Speed = Distance / Time interval

Speed = 3.65 meters / 0.2 seconds = 18.25 meters per second

Therefore, the calculated speed is 18.25 meters per second or 40.8 MPH, which sounds about right for a high school dude.

AH! Framerate..not seconds! Thank you!

Distance=3.8m (hypotenuse) not 3.65..

42.8mph

but yeah, you’re so right.

I have to figure out a better timer. .20 seconds...seems to long. Watching the video...its faster than .2s.

any ideas?

ouch on R, but 42 mph is probably correct. The numbers make sense, .2s is accurate. Most likely range is 40mph to 55mph with variables. Say 5 frames, using measurements, and that will get 53mph. 53mph would be olympic level female speed from looking around the net.

Also depends on what brand and model ball was hit.

So what’s the related question... Is it that boys shouldn’t be playing with girls because girls can’t react fast enough? Or is that if a boy gets hit on the head like that, he can withstand the hit better than a girl can? Or is it something else?
