A medieval trebuchets arm is connected via an axis at 2/3 of the total length of the arm. The arm is 3.36m long. Connected to the top of the arm is a sling which is also 2/3 of the arm in length. Whatever stored in the sling when throwing is released when it is in a 45 degree angle to the arm (Which gets it the most distance). The ratio of counterweight to projectile is 100 to 1. In this catapult the counterweight is 200kg and the projectile weighs 2kg. How much kinetic energy is stored in the projectile at the point of release?

Question

anonymous · Answer

How far away is the target?

anonymous · Answer

Might you have a diagram for this scenario?

anonymous · Answer

Is the boulder placed at the end of the short arm and then released from rest, or is it dropped into that position from a particular height?

anonymous · Answer

Are we given any initial conditions, such as initial orientation of the arm?

anonymous · Answer

It looks to me like the problem as stated does not have enough data to determine a specific numerical value for the energy  or velocity of the projectile.

If that is truly the case, then the answer to your question can only be written in symbols that represent the missing data.
