Consider the system below with three masses. Masses m1 and m2 slide across a horizontal frictionless surface. Mass m3 hangs vertically from the second rope. When the system is released, it is observed that the hanging mass m3 has an acceleration of 5.00 m/s 2 downward. (a) Consider the forces and acceleration of the hanging mass m3 by itself. Find the tension in the rope that runs between masses m2 and m3. (b) Consider the forces and acceleration of mass m2 by itself. Find the tension in the rope that runs between masses m1 and m2.
