(f) And 2 1 2 BB mv K = yields v B = 2/ i Gm R . (g) The answer to part (f) is incorrect, due to having ignored the accelerated motion of “our” frame (that of body A ). Our computations were therefore carried out in a noninertial frame of reference, for which the energy equations of Chapter 8 are not directly applicable. 101. (a) Their initial potential energy is Gm 2 / R i and they started from rest, so energy conservation leads to 22 2 total total . 0.5 iii Gm Gm Gm KK RRR −=− ¡ = (b) They have equal mass, and this is being viewed in the center-of-mass frame, so their
