Question

I have gotten this to work nicely, but when speed hits a certain speed it want it to stay that speed and not increase. The code does this to an extent, but when I am printing out the values one the the values hit 270 and then drops back down to 250. I do not want it so surpass 250 ever. Also the decent variable keeps moving up should it not stay the same value when max speed is hit or is this right and it is behaving right it just looks wrong to me? What I am getting at is should the distance traveled be more if the object has hit terminal velocity which i set to 250 every second ? Or do I have to set up the code differntly? Like have an if statement in there to say if mySpeed = maxSpeed then only use a certian decent rate? Well this is straight out of a physics book so…
Thanks for any help

Take out the else, you were allowing it to pass the max for that one iteration:

        if (maxSpeed > mySpeed){
            mySpeed = g * t;
        }
        if (mySpeed >= maxSpeed) 
        {
            mySpeed = maxSpeed;
        }
