Its kind of hard to know whats happening as I don't know how you've got the movement set up.
You say physics, but that would lead me to believe its not a constant speed. So the 10 * 30 may be questionable.
Or perhaps the angle you are using is off as well.
All I can say is a rate of 10 pixels per second for 30 seconds should get you a distance of 300 pixels, and and angle of 95 would point south east if the origin was the east, or that way ->.
Thats the origin C2 uses.
