Consider a system consisting of three particles: m = 3 kg, v = < 9, -4, 14 > m/s m2 = 9 kg, v2 = < -13, 7, -6 > m/s m3 = 4 kg, v3 -< -24, 35, 21 > m/s (a) What is the total momentum of this system? F tot = kg · m/s (b) What is the velocity of the center of mass of this system? cm = m/s (c) What is the total kinetic energy of this system? Krot = (d) What is the translational kinetic energy of this system? Ktrans = (e) What is the kinetic energy of this system relative to the center of mass? Krel = One way to calculate Krej is to calculate the velocity of each particle relative to the center of mass, by subtracting the center-of-mass velocity from the particle's actual velocity to get the
