I've been trying to figure out how to calculate a trajectory based on angle and speed, like you might do for artillery or something...
From what I've read so far, you can calculate x and y positions like this:
y = y_velocity*time - 9.8*t^2/2
x = x_velocity*time
Is that correct?
Where I'm lost is how to get the x and y velocities based on the angle to the ground and the force that is applied...
Anyone have any ideas, or is there a better way to do this?
