Thus, finding the maximum throwing distance is equivalent to finding the combination of v0 and α that maximizes s. Intuitively, you might think that the angle of release should be α = 45°. Reading cookbooks is one of my favorite things to do. You can fix this by pressing 'F12' on your keyboard, Selecting 'Document Mode' and choosing 'standards' (or the latest version The trebuchet is a large siege weapon that you might recognize from movies set in the Middle Ages or fantasy worlds.

In principle the whipper has some similarities to the King Arthur, but none to the FATs. Not only is this trebuchet simple, it is extremely efficient.
