(b) Find the linear momentum of the system of particles at the instant described above. (c) Find the angular momentum of the system of particles about the origin at the instant described above. (d) Find the angular momentum of the system of particles about the center of mass at the instant described above. (e) If gravitational forces are the only forces acting on the system, what can you say about the future motion of the system? What quantities will be conserved? Page 1 of 1...
