I have a projectile starting at a certain location. I know the original x and y, the initial power, gravity, and also the wind speed. I need to be able to plot a point where the projectile is going to be at a certain time taking into the account all of these values. Technically I found the two equations that should be used, but for some reason instead of going in an arch the projectile goes in a curve upward from the origin. I've checked all the values and they are all accurate. Can someone give these two equations and explain them? Thanks.
