Three objects are connected as shown in the figure below. They move along a horizontal, frictionless surface, and are pulled to the right with a force Fext = 2.4 N. With the three mass values given as m1 = 604 g, m2 = 744 g, and m3 = 693 g. Calculate the magnitude of the acceleration of the three objects.
The description is inadequate, I have no idea how the objects are connected.
If they are in a line, a=force/total mass.
