A 1500 kg point mass (
 
  A) and a 1200 kg point mass (B) are held in place 1.00 m apart on a frictionless table. A third point mass is placed between the masses 20.0 cm from B along the line connecting A and B and then released. Find the magnitude and direction (toward A or toward B) of the acceleration of the third mass just after it is released.
