[Please Help!] Find Initial Velocity (With Wind Factored In)
I can't do it =\.
Q: What equation would I use to find initial velocity? Given: Wind Speed, Wind Angle, Coordinates of Origin, Coordinates of End Point, (Distance), Projectile Mass, Theta (Angle to Use)
Here's my repost from a previous topic:
Hey Physics Forums. This is my first post here, and I'm just wondering about how to find what the initial velocity SHOULD be based on all the other information that I provide (it's for a program application I coded).
Anyways, I have this right now (which is for no wind/0 wind):
I am just wondering how I would go about factoring in the "wind" and wind's angle.
Wind Angles:
^ 90
< 180 > 0
\/ 270
As you can see, the wind angle starts at East 0 and increases counter-clockwise.
Anyways, here's the formula:
Velocity = Sqrt((Mass * (DifferenceInX^ 2)) / (2 * (DifferenceInX) * Sin(Theta* PI / 180) * Cos(Thtea * PI / 180) - (2 * (DifferenceInY)) * ((Cos(Theta* PI / 180) ^ 2))))
Where Theta is the angle of the shot; Difference in X is the difference in coordinates X of the starting position and where you want the shot to end; and DifferenceInY is the difference in coordinates Y of the starting and ending position.
Please help me out! Thanks.
I don't take a Physics course yet, I'm enrolled in Algebra 2 at the moment, but am heavily interested in the Physics course of study, so please do help me out!
I need an equation, like the one above, that will work in my computer program.
