Identical twins, each with mass 61.0 kg, are on ice skates and at rest on a frozen lake, which may be taken as frictionless. Twin A is carrying a backpack of mass 12.0 kg. She throws it horizontally at 3.20 m/s to Twin B. Neglecting any gravity effects, what are the subsequent speeds of Twin A and Twin B
