Problem 2: How do the convertible and center of mass kinetic energies compare in different inertial reference frames? Select One of the Following: (a) They both have the same value in all inertial reference frames (b) me, has the same value, but Km has different values in different frames (c) Kcm has the same value, but Kmm has different values in different frames (d) They both have different values in different reference frames of mass cannot Change, so if the center of mass was moving before the Collision, it must still be moving afterwards; and, as mentioned in this chapter's introduction, as long as there is motion in a System, its total kinetic energy cannot be zero. Km (1 ) 0'5 0.4 0.3 0.2 0.1 1 (ms) Figure 4.5: The total kinetic energy as a function of time for the collisions shown in Figures 1, 3 and 4, respectively
