Why isn't the initial velocity zero? Hang time only depends on motion in the y-direction: Δy = 0, assuming cannonball falls back down to same level. You heard it from two witnesses. Average Patience, also known as Average Time to Abandon (ATA), is the average length of time that a caller will stay in a queue before they will abandon (or hang up the call).

(given), g = acceleration due to gravity = 9.8 m/sec^2 (constant), first question: d=1/2*a*t^2 (this is going in the up direction only, multiply by two for total time) t=(2*d/a)^0.5 = (2*(0.78m)/(9.8m/s2))^0.5 = 0.399 sec (up time only) total time = 2*0.399 sec = 0.78 sec For second question: t=v/a (time in going up only) = 6.0m/s/(9.8m/s2) = 0.612 sec d=1/2at^2 (going up only) = 1/2*9.8*(0.612s)^2 = 1.84 m Hope this helps.

If you check out the first THT Annual, you’ll find an article from Robert Dudek about the importance of hang time in how easy it is to field a fly ball (which, for these purposes, I am using to encompass everything that isn’t a ground ball). © 2008-2010 http://www.science-mathematics.com . Exit Velocity (EV) How fast, in miles per hour, a ball was hit by a batter. let 0 = vsinθ - ½gt to find out when it lands. We make it about 800'. Well, now we have Hit F/X. For a line drive type of hit, the hang time is even more senstive to the spin (at least, percentage-wise). How much does does a 100 dollar roblox gift card get you in robhx? Which group of elements is the least reactive and .. Why can you only see the stars some nights. If you open your book on projectile motion, the formula for "hang time" or maximum time that object is in the air is given by the formula, V = initial velocity = 24.4 m/sec.

Hang time only depends on motion in the y-direction: Δy = 0, assuming cannonball falls back down to same level. I plugged it in to my main equation and it was wrong both when I used 1/2 time and given time.

UPDATE: Professor Nathan, from a comment at Tango’s blog: Colin: I am not sure exactly how you did your calculation, but I am pretty sure that neglecting the spin is not a very good approximation. E.g., a line drive hit 3 ft off the ground at 0-deg has a hang time of 0.44 and 0.74 with 0 and 2000 rpm of backspin, respectively. Optionally, type the initial … What will you do. I can’t tell you which is more reliable, or even if either set of estimates is more useful than what we currently have for air balls.

T = 2V(sin Θ)/g. How to calculate hang time? Calculate the hang time of an athlete who jumps a vertical distance of 0.76 meter. I really don't understand this problem, nothing seems to work. For a line drive type of hit, the hang time is even more senstive to the spin (at least, percentage-wise). The athlete goes up 0.75 m, and then comes back down the same distance.

For those interested, you can download the source code used to calculate hang time here. you can download the source code used to calculate hang time here. MATH QUESTION HELP!

Clearly, there are two points in time when the projectile is at ground level.

The punter on a football team tries to kick a football so that it stays in the air for a long "hang time." Enter the angle. The only influence on the vertical motion is gravity, which provides a constant acceleration downward.

Calculate the hang time of an athlete who jumps a vertical distance of 0.76 meter.

In order for it to work you need: Go ahead and leave a comment or drop me a line if you have any questions or helpful suggestions regarding the Python code. This can potentially be estimated based upon the spin of the incoming pitch and the launch angle (smarter men than I will be required for this task). How to calculate hang time? Ano ang mga kasabihan sa sa aking kababata?

Clearly, there are two points in time when the projectile is at ground level. What is the "hang time" of an athlete who can jump a vertical

A little longer time is mostly for ground balls.

What I find is that the actual hang time is longer (as you would expect) by an average of 20% (sometimes as much as 40%, sometimes as low as 0%). For those who want to see the data, you can.

As a little taste, here’s a look at DER for a ball in play (in other words, home runs excluded) based upon hang time: The smallest time in the air looks like it’s largely bunt attempts. by Retrosheet.

Just relax and look how easy-to-use this maximum height calculator is: Choose the velocity of the projectile. by Handedness, defense is harder to measure than infield defense. There is of course a lot more we can do with this data, and a lot of improvements that can be made to how the data is derived from Hit F/X. Assume that it has a muzzle velocity of 860 meters/second, and that it is pointing straight up. For the time being, I am proceeding as though a hit ball has no spin.

distance of 0.75 m? Here is a question on my homework and I can't figure it out!

As a result, you can calculate things like the time the projectile will be airborne before it strikes the ground. This gives us a few pieces of data that we can use to estimate hang time: The most important piece of missing data is the ball’s spin at launch. V = initial velocity = 24.4 m/sec.

This result can also be obtained by showing that the initial vertical speed is equal to the final vertical speed but opposite in direction: vf = -vi, since the projectile moves up on the way up and down on the way down. (given) Θ = angle of launch = 57.5 deg (given) g = acceleration due to gravity = 9.8 m/sec^2 (constant) Substituting values, The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply.
