Mass 1 = 10.0 kg Mass 2 = 3.00 kg The pulleys and rope are massless, and there is no friction. What is the tension in the rope? What is the acceleration of mass 1? If my thinking is correct, the tension is half the weight of mass 2 (14.7 N), and the acceleration of mass 1 is 1.47 m/s^2. My textbook gives the solutions as 13.7 N and 1.37 m/s^2.
