Anna (mass ma = 65kg) is skating through the airport at a speed of V_A = 8 m/s. She sees an unattended suitcase (mass m_s = 15kg) and decides to scoop it up. She successfully picks up the suitcase, and now she and the suitcase are moving along with the same velocity. Ignore friction in Anna's skates. First, determine if mechanical energy is conserved in this scenario or is the momentum conserved in this scenario? Then based on your decision, use the correct conservation law to find the final speed of Anna and the suicase and then determine how much thermal energy was generated in this scenario?
