Calculate the Range of a Trebuchet

A more complete output and record of the input can be obtained below. Copy and paste it into a text document
to record your trials and experiments. If you get a really good one with a very high efficiency (>75%), then you
to increase the accuracy of the simulation by increasing npts--up to 1600 is allowed. If you do better than 75%
while using npts =1600, please
send a copy to me!
Note that the units of the range is the same as the length units input--
metric (English) in means metric (English) out.
To get more details, the angles and their derivatives can be output here. Copy and past
them into a spreadsheet for graphing. Only 40 points out of those calculated are
output into the table, however. If you are really motivated, these data can be used to
readily calculate every
other property of the motion and the energetics. It can also be used to infer the
reliability of the convergence of the algorithm: if there are rapid changes or kinks in
theta or psi, then there may be some inaccuracy in the integration of the differential
equaton.
