You decide to shoot your pellet gun at a target on the wall of your backyard. You are sitting in a tree, 5.60 m high. You are aiming directly at the center of the bull's eye, which is located 1.20 m above the ground. The tree is located 9.10 m away from the wall. Your pellet gun has a muzzle velocity of 13.5 m/s.

a) how long is the pellet in the air?
i got 1.55 s

b) does your pellet even reach the wall? if so, then determine how far up it hits and the velocity your pellet had when it struck. If not, determine how far from the wall it struck the ground, and with what landing velocity


c) at what angle with the horizon should you aim your pellet gun to hit the bull

these last two i don't know what to do

Yes, I saw it as soon as I got cos^2Asin^2A,cosAsinA and sin^3A. I first thought that a quadratic in sin would be okay, but then, cosAsinA showed up and blocked everything.
