can u help i would like either a mathamatision or photographa [check out mi spelling haaaaaaa] to work out the depth of my birds i will pay u [very little] take u out for a meal n get u drunk [after u have done the calk] n u must prove the calk to me thanks dont all rush xxxxxxxxx

Norman I asked a physicist in work once if he could calculate the depth using the stopwatch he did tell me how to do it but I have forgot. I will try to see him to-morrow, but I do remember it was very difficult with the rollers as a lot of factors came into force such as if the wings went out further on one bird compared with another this would be a factor as to rate of fall and any calculation would only be approximate, but it would give you a good idea

cheers dave i think the time is ok but like a sprinter will cover more ground than a jogger in the same time n this is the same birds with the birds tight n fast to loose n baggy

hey norman have you been going to night school your spelling is improving lol or did lana do it. ask the africans they used to fly comps to a clicker system so many feet per second. but like dave said it all depends on the style of roll.

Norman i think the future way to get an accurate measurement of a roller in full roll is by using a laser.
How to do it Ive not got a clue.
Do i qualify for the meal and the piss up lmao

the only true way would be with a camera with rappid shutter speed n calk the distance from camera to birds otherwise were all guessing wich i aint got a prob with each to their own xxxxx

Norman I spoke to three physicists including a Dr of physicists and they were facinated when I told them what I was trying to do.
First of all they all agreed the only true way of getting any way near an accerate figure is by timing
and this is what they came up with
starting vertical speed = 0
acceleration of gravity = 10m/5squared
after lots of calculations it works out as
1 second roll = 5m
after this speed becomes constant and a 2 second roll would be 20m but this may be slightly less because of feathers,also the spinning action of the bird may decrease the rate of descent very slightly and because it is only a very short period of time the laws of gravity would not affect the distance very much, but the one thing they all agreed on the object could not descend any faster than this so after about 3/4 hour of these calculations my brain said thats it and left them to it

cheers dave none the wiser i think u need to show them ur birds rolling before they work out an equation for it i think this is calculated on a dead weight ithink 16ft in 1 sec is a bit mutch i believe my birds are of a decent depth n speed n with the 1 and 2 are at about 12-15 ft if u go shooting those ducks n pheasants take ages to hit the ground because of the speed of the roll surley this actually can hold them rather than force them down [if i showed this much interest at school i would not of had to stand outside the classroom n may of got some gcse haaaa heeeeeeeee lolllllll xxxxxxxxx]
