How do you find the initial speed for a certain range?
The problem I'm stuck on the shooting involves a water pipe at 45 degrees in a bucket that has a diameter D and height 2D. This is a far distance 6D. I need to find the range of speeds initial requirements for water in the bucket (in terms of development, of course). I feel I am missing a vital piece of information. Any help is appreciated! Thank you!
If you elliminate "t" from the EQS kinematics, Y = V (o) Tsin (45) - (1 / 2) gt ^ 2 x = V (o) TCoS (45), you get y = x - (gx ^ 2) / (V (o)) ^ 2 V (O) ^ 2 = (gx ^ 2) / (XY) V (o) = Sqrt [(gx ^ 2) / (x-2D)] So now I find V (o) for distances x = 6D-(1 / 2) D and x = 6D + (1 / 2) D, assuming that the distance "6D" is at the center of the bucket.
