13. (Force and Motion I) Consider the system shown in figure with ma = 9.5 kg and mg = 11.5 kg. The angles 0A 59 and B = 32. i Draw the free body diagrams for block A and block B. ii In the absence of friction, what force F would be required to pull the masses at a constant velocity up? me iii The force F now is removed . What is the magnitude and direction of acceler- ation of the two blocks? iv In the absence of F, what is the tension in the string? Answer: ii) 140 N iii) a = -6.7 m/s2i iv) 17 N
