The force needed on the ball (for 45 degrees) was 10#, which is about 15x the weight of the boulder. Including the weight (or more properly moment of inertia) of the throwing arm would actually be the next most important feature to add, with gravity being well behind that. Both of these are taken care of in the 2x target for force.
