Unformatted text preview: which yields v = 2.7 m s . The second part involves mechanical energy conservation: 1 1 2 (3.0 kg) (2.7 m s) 2 = (200 N m) xm 2 2 which gives the result xm = 0.33 m. 9P63. (a) The center of mass velocity does not change in the absence of external forces. In this collision, only forces of one block on the other (both being part of the same system) are exerted,...
