moves under the action of three forces

as indicated in the figure.
At a given instant, the velocities of the three particles are :

For that instance, determine :
  1. The linear momentum of the system of particles.
  2. The velocity vector of the center of mass of the system of particles.
  3. The acceleration of the center of mass of the system of particles.
