28.0 kg 15.0 kg Atwood's Machine. A 15.0-kg load of bricks hangs from one end of a rope that passes over a small, frictionless pulley. A 28.0- kg counterweight is suspended from the other end of the rope, as shown in the figure. The system is released from rest. 8. What is the tension in the rope while the load is moving? a. 150 N b. 191 N not sure C. 241 N d. 345 N e. No AnswerConsider the system shown in figure. Block A weighs 45.0 N and block B weighs 25.0 N. Once block B is set into downward motion, it descends at a constant speed. 9. A cat, also of weight 45.0 N, falls asleep on top of block A. If block B is now set into downward motion, what is its acceleration (magnitude and direction)? a. -2.13 m/s*2 b. -4.56 m/s^2 C. -6.78 m/s^2 d. -8.45 m/s^2 e. No Answer A B
