There's a formula here:
http://en.wikipedia.org/wiki/Trajectory
(where v0 is the initial speed, theta is the angle of elevation and g is the acceleration due to gravity).
Or in BASIC code:
Code:y = - (x^2) * g / COS(theta)^2 / (2 * v0^2) + x * TAN(theta)
Or in an entire program:
Code: MODE 8
v0 = 110
g = 9.8
theta = RAD(60)
a = TAN(theta)
b = g / COS(theta)^2 / (2 * v0^2)
FOR x = 0 TO 1278 STEP 2
y = x * a - x^2 * b
DRAW x,y
