1. The problem statement, all variables and given/known data A 55-kg girl is standing near and to the left of a 75-kg boy on the frictionless surface of a frozen pond. The girl tosses a 1.8-kg ice ball to the girl with a horizontal speed of 7.5 m/s and he catches it. What are the velocities of the boy and the girl immediately after the boy catches the ball? 2. Relevant equations MgVog+MbVb=0 Vfg=MballVb-Mb / Mg 3. The attempt at a solution 1.8kg x 7.5 m/s - 75kg / 55kg = -1.1 Vfb=1/2 MbVb/ ( -1.1Mg-Mb) = -10x10^-2 I don't think I did this correctly, can someone walk me through this?
