Two blocks are connected by a light string and accelerated upward by a pulling force F. The mass of the upper block is 50.0 kg and that of the lower block is 100 kg. The upward acceleration of the system as a whole is 1.50 m/s 2. Neglect the mass of the string. (a) Draw the free-body diagram of each block. Use the diagrams to determine which of the following is true for the magnitude of the string tension T compared to other forces: (1) T w 2 and T F ; (2) T w 2 and T F ; (3) T w 2 and T F ; or (4) T = w 2 and T F (b) Apply Newton's laws to find the required pull, F. (c) Find the tension in the string, T.
