Eli_The_Moose: I'll inspect the site to make sure no rubbish is left behind, but this cache has had it. Too expensive for me to replace

Geocache Description:

There is no cache at the above coordinates, only a car-park. Solving the puzzle requires some elementary notions of high-school physics.

Warning: plundering a castle is an inherently dangerous business, and may require battling your way through an array of defenses.

In a dark, hidden chamber, deep inside the tallest tower in Flagstaff’s castle, there is a shrine full of gold-coins. To get to the treasure, you will need the following specialist equipment: a catapult, a ram and a ladder.

A catapult stationed at the above coordinates will hit the castle, if it shoots at maximum range (X meters) at 48ºtrue. Assume equal initial and final elevation for the projectile’s trajectory, and the projectile’s initial velocity is V.

A ram beginning its run with 855m head-start and the same initial velocity V but slowed down by scrub (coefficient of dynamic friction m=5) will also come to a halt exactly at GZ. The ram is not propelled by any external force, and is bound to a horizontal surface.

Once at GZ, take out that step-ladder to reach the top of the castle’s highest tower. You’ll find a camo jar with the coordinates for the nearby final stash.

You won’t actually need a ladder, but the presence of a mate might help. I recommend you only attempt this cache in dry weather. Keep kids under supervision, and small children are better left at home.

Please take your time to return the waypoint and the cache as you found them. They should both last a long time. Pencil and paper might help in the final quest for the treasure.
