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?”

Question

(b) Determine the acceleration vectors of all mobile bodies in the situation where
they are always in contact as shown in Fig .1.
(c) Calculate the normal reaction forces on block ? and ?1; tension in the string
and contact force between block ? and ?2.

2. Fig. 1 shows a three-body system where m, and m; are connected by a string and both are
sliding on the different surfaces of block M. A force F is applied on block M and the whole
system moves to the right. Magnitude of the force F is 250 N and the masses, M = 20 kg,
m, = 3 kg and m; = 4 kg. All surfaces are frictionless, the pulley is massless, and the string
