Two travelers fight over what they think is their 3.9 kg suitcase. Traveler1 pulls to the right with a force of 2.1 N, and traveler2 pulls to the left with a force of 8.2 N.  No other forces are involved.  Determine the magnitude of the suitcases resulting acceleration(in m/s²).

Three points are arranged in 2 dimensions, with the following masses and coordinates:

m_A=50 kg, located at (0, 0)

m_B=60 kg, located at (100, 50)

m_C=20 kg, located at (100, 100)
