Suppose that for the couple in the figure below, you were told that the girl's mass was one-half that of the boy's mass. The boy has a velocity of v = 0.38 m/s to the left. What would be the girl's velocity in this case? (Consider the ice to be frictionless. Enter the magnitude only.)   Two ice skaters, a boy on the left and a girl on the right, face each other in figures a and b, which depict, respectively, before and after pushing off from each other. Before: The two ice skaters face each other with the palms of their hands facing towards each other and touching the other person's palms. After: The two ice skaters have pushed off and now have their arms outstretched facing each other. A left-pointing arrow above the left skater is labeled "v". A right-pointing arrow above the right skater is labeled "?".
