Maybe for tests since it’s in notes.1. Consider a system of particles.The system is general.The particles may be rigidly bondedtogether. They may be non-rigidly bonded together. They may only interact through collisions.They may not interact at all. It’s a general system.a) Assume the center-of-mass version of Newton’s 2nd law holds for each particle and writeit down for particlei.b) Write down the net force on particleias an explicit sum of external and internal forces.The external forces are due to particles or fields external to the system and the internalforces are due to other particles in the system.c) Prove that the sum of all the internal forces for the system is zero.d) Prove thatvectorFnet=summationdisplayimivectorai,wherevectorFnet
