a ballistic calculator
think this is too vague to answer as I can imagine the ballistics depend on: (quick braindump)
- environment values like temperature, wind force and direction (of all airlayers involved), rain/hail/snow, are there trees, mountains in the trajectory
- object parameters like weigth, form, point of gravity(?), rotation, interactiveness in air (does it loose weight like a rocket, does it change form like a snowball)
- the device that "shoots" the object may influence, angle, speed, acceleration
with respect to the calculator, what needs to be calculated?
- place of impact?
- want a simulation?
- may it be slow, or must it be real time, or faster?
quite some questions to answer ...
nevertheless, I expect an Arduino can do it to some extend as the very first ballistic computers were less powerful than an Arduino. but you first find the right math.DISCLAIMER: in some countries ballistic algorithms may be considered illegal to have/use/export
