The computing project concerns the theory of particle dynamics. The concept is to model projectile motion including the nonlinear re- sistance caused by an elastic cord anchored at a single point, pulling on the particle. This system models the sport of tetherball, except that the cord does not wrap around the pole because of the universal joint at the top of the pole.

can get help with it?

%  Projectile(4) (No Fluid Drag)

%   This program computes the motion of a particle subjected to 

%   gravity forces and set in motion with initial velocity from an  

%   initial position. Numerical integration (time stepping) is done

%   by the generalized trapezoidal rule (GTR).
