WEll, the initial vertical velocity determines how long it is in the air.
Vy=60*sin30=30ft/sec
Vyf=Vyi+Vy*time-4.9 time^2
0=0+30t-4.9t^2
solve for t, the time in air.
Now, horizontal distance
d=Vix*time
where
vix= 60*cos30
Vy=60*sin30=30ft/sec
Vyf=Vyi+Vy*time-4.9 time^2
0=0+30t-4.9t^2
solve for t, the time in air.
Now, horizontal distance
d=Vix*time
where
vix= 60*cos30
