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.
