What is the skaters final velocity

Reference no: EM13276390

A skater of mass 86.0 kg initially moves in a straight line at a speed of 4.70 m/s. The skater approaches a child of mass 44.5 kg, whom he lifts on his shoulders. Assuming there are no external horizontal forces, what is the skater's final velocity?
