[quote=“xv84”][quote=“jamesh23”][quote=“xv84”]You should check your math. 65 feet / .70 does NOT equal 92 MPH. It equals 92 FEET per second. Actually it should be rounded to 93. You need to convert it to MPH.

93 ft/s X .682 = 63.4 MPH.

There is a more accurate way to time it. If you have video of yourself, just count the frames from release to whatever you’re throwing at and multiply by .033. That’s if the video was recorded at 30 frames/sec, which is the normal rate. If the rate is different you’ll have to use different values. This will give you the time it took the ball to travel. Now take the distance and divide it by the time. That gives you average speed in feet per second. Now you have to multiply by .682 to get MPH. Or you can use this converter

.

Here is it in mathematical form:

(Distance) / (Frames * .033) * .682= MPH[/quote]

so whats the entire equation?[/quote]

Sorry, but do you guys need glasses or improved reading comprehension? Like Spencer said, I already gave you the equation. But you can’t use it unless you have video recorded at 30 frames per second. Again, I already mentioned that as well.

Here is it in mathematical form:

b / (Frames * .033) * .682 = MPH[/b]

If you are using Jasonlinaker’s method it would just be:

b / (Seconds) * .682 = MPH[/b][/quote]

No i thought you meant you had to add that to his equation for it to be right, not that they were 2 completely different equations. :roll:
