Consider a system consisting of three particles:
m1 = 5 kg, 1 = < 9, -7, 14 > m/s
m2 = 3 kg, 2 = < -12, 7, -5 > m/s
m3 = 5 kg, 3 = < -28, 38, 17 > m/s
What is the velocity of the center of mass of this system?
What is the total kinetic energy of this system?
What is the translational kinetic energy of this system?
