1. A duck flies horizontally with velocity v at a height h. When a duckhunter is right below it, he shoots with his shotgun. What is the minimum initial velocity V0 of the bullet and the angle a at which he shoots so that the bullet hits the duck? Obviously, given are v, h and gravity acceleration g. 2.I think I just need to take that Xduck = vt, Xbullet = V0xt, Ybullet = V0yt - 1/2 gt2, Vy = V0y - gt for the bullet. 3.I just took Xduck = Xbullet, Yduck = Ybullet, and Vy > 0 for the bullet but I still get a result different than the one in my book.
