You go to the local petting zoo where you anger an alpaca by throwing rocks at it from the safety of a ladder. The alpaca is 2.05 m tall, and spits at you from 6.02 m away at an angle of 25 degrees above the horizontal. You are 3.05 m above the ground because of the ladder. How fast did the alpaca spit if it hits you in the face?

Actually, that'll just give you the distance, not the speed. Sorry.

Hmm... yeah, actually disregard that. It looks like that angle doesn't fit into that triangle.  :/
