Identical twins, each with mass 56.2 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 3.50 m/s to Twin B. Neglecting any gravity effects, what are the subsequent speeds of Twin A and Twin B?
Twin A m/s
Twin B m/s

    Try using the law of conservation of linear momentum, twice. First after the backpack is thrown, and again after it is caught. Show your work if you need further help.
