Three blocks of masses m1 = 2 kg, m2 = 4 kg, and m3 = 6 kg are connected by strings on a frictionless inclined plane of 60 as shown. A force of Fapplied = 120 N is applied upwards along the incline to the uppermost block, causing an upward movement of the blocks. The connecting strings are massless. You must use the component method together with the appropriate Newton’s law. (a) Calculate the acceleration of the blocks.  (b) Calculate the tension in string 2.

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?”
