• In order to submit a paper to the contest it is obligatory to send it together with the proposal form enclosed below, signed by all participants, to the following address: 
   

  Ángel Manuel Ramos del Olmo Departamento de Matemática Aplicada Facultad de Matemáticas Universidad Complutense de Madrid Plaza de Ciencias, 3 28040-Madrid Correo electrónico: angel@mat.ucm.es

A signed printed copy either in Spanish or English has to be sent with a copy in computer format to the above e-mail address, enclosing, if the case be, the material of graphic, audiovisual, computer or any other nature deemed appropriate.

• The deadline for submitting the papers is October 28th, 2008.
• The decisions about the winning papers will be taken by the Mixed Monitoring Committee of the Agreement No. 5901 of the UCM,  consisting of:

• On the side of the Universidad Complutense de Madrid:
  • Juan Antonio Tejada Cazorla (Dean of the Mathematics Faculty), or person to whom he might delegate. 
  • Jesús Ildefonso Díaz Díaz (Co-director of the Investigation Team of the UCM), or person to whom he might delegate. 
  • Ángel Manuel Ramos del Olmo (Co-director of the Investigation Team of the UCM), or person to whom he might delegate.

Determinate the path of the centre of mass of a rigid solid, with axial symmetry, equipped with an angular momentum on its centre of mass and with respect to a principal axis of inertia, when some other forces are applied on it and such that, they would have a null resultant when applied to the centre of mass, but that applied on other points, they generate an angular momentum non-coaxial with the existing one in the solid. It must be assumed that the distribution of velocities generated by this new non-coaxial momentum is composed with any other velocity on the centre of mass of the rigid solid.
