Masses m1 and m2 lie on a frictionless, horizontal surface and are tied together by a horizontal rope labeled rope 2. m2 is then connected via a pulley by a rope, labeled rope 1, to a vertically hanging mass, m3. If m1 = 11.1 kg, m2 = 7.4 kg, and m3 = 12.8 kg, what is the tension in rope 1 in Newtons? (The masses are not in equilibrium so the acceleration is not zero.)
