Question
What is the approximate horizontal distance traveled by a soccer ball that is kicked at an angle of 30 degrees with an initial speed of 60 feet per second?

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
