A hunter aims directly at a target (on the same level) 120 m away. (a) If the bullet leaves the gun at a speed of 290 m/s, by how much will it miss the target?

Question

(b) At what angle should the gun be aimed so the target will be hit?

Answer 1

distance = rate x time
120 m = 290 m/s x time
time = ??

The gravitational force will be acting on the bullet during that time. The distance it will fall is
S = 1/2 (g)t^2
I get something like 0.8 m or about 80 cm.
Check my thinking. Check my work.
