I’m trying to simulate a projectile launch like this ( http://galileo.phys.virginia.edu/classes/109N/more_stuff/Applets/ProjectileMotion/jarapplet.html ). I googled but the results aren’t specific.
What would you set the x and y of an object when time ( t ) is updated, assuming you have these vars:[LIST]
[]angle ( a )
[]velocity ( v )
[]x0 ( initial x )
[]y0 (initial y)
[*]Not sure if necessary, but if so gravity (g)[/LIST]_____________________
Also, given a projectile at its initial position’(x0, y0) and angle ‘a’, how can I solve for the velocity (v) to make it pass through a point (x, y)?
Thanks.
