) In the Atwood machine shown here, if M = 1.50 kg and m = 1.20 kg, what is the magnitude of the acceleration of the system? (Assume the pulley is frictionless). [Hint: We did the same type of problem in lecture.] Remember your answer as you will need it for the next question.  0.11 m/s 2  0.54 m/s 2  1.09 m/s 2  2.02 m/s 2 B) In the Atwood machine described above, use your acceleration answer from the previous question to find the tension in the string. (Hint: draw a force diagram for one of the masses.)  13.1 N  14.7 N  17.1 N  6.5 N

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
