Two masses, m1 = 3 kg and m2 = 11 kg, are attached by an ideal string slung over an ideal pulley. A second ideal string is attached to m2 and slung over a second ideal pulley, with an applied force, Fapp, at the other end. What must be the magnitude of Fapp in order for m2 to have an acceleration of 2 m/s2 in the upward direction? (Note: Answer in units of N.)
