Question
Consider a system consisting of three
particles:
m1 = 3 kg, 1 = < 7, -6, 15 > m/s
m2 = 3 kg, 2 = < -15, 6, -6 > m/s
m3 = 3 kg, 3 = < -21, 35, 20 > m/s
(a) What is the total momentum of this
system?
tot =
kg · m/s
(b) What is the velocity of the center of mass
of this system?
cm
cm =
m/s
(c) What is the total kinetic energy of this
system?
Ktot = J
%3D
(d) What is the translational kinetic energy of
this system?
Ktrans = J
(e) What is the kinetic energy of this system
relative to the center of mass?
Krel = J
