time in air:
hf=hi+2000sin30*t-4.9t^2
hf=hi=0
t=2000sin30/4.9
range:
d=2000*cos30*timeinair
hf=hi+2000sin30*t-4.9t^2
hf=hi=0
t=2000sin30/4.9
range:
d=2000*cos30*timeinair

the fine article in wikipedia on "trajectory" explains this and more. The formula for the range is
R = v^2/g sin(2θ)
R = v^2/g sin(2θ)
