An arrow is shot with an initial speed of 25 m/s (and lands at the same height as its launch height). There are two possible angles at which it chould be aimed so that it goes 30 meters. What are they?
Givens:
v(i)=25m/s
a=-9.8m/s^2
d(x)=30m
I know the first step is to determine the time the arrow is in flight, but I'm not exactly sure which formula to use in order to find time.
