For those that don’t have Fitzpatick, the question was;
A stone is thrown so that it will hit a bird at the top of a pole. However, at the instant the stone is thrown, te bird flies away in a horizontal straight line at a speed of 10 m/s. The stone reaches a height double that of the pole and, in its descent, touches the bird. Find the horizontal component of the velocity of the stone.
Having thought about this with a fresh mind, it reminded me a bit of last year’s HSC question which was a projectile motion question where you didn’t need to use projectile motion, but rather used ideas about he quaratic function (i.e. parabola).
Hope you like the solution, I think it ended up being quite neat.

Moral of the story; if you are sitting on a pole and someone throws a rock at you, fly towards the thrower NOT away. Dumb bird!!!!
