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?”

Two blocks of mass M₁ and M₂ are connected by a massless string that passes over a massless pulley as shown in the figure. M₁ has a mass of 3.75 kg and rests on an incline of 0₁ = 65.5°. M₂ rests on an incline of 02 = 23.5°. Find the mass of block M₂ so that the system is in equilibrium (i.e., not accelerating). All surfaces are frictionless. M2 M₂ = kg
A child is playing on a hill with a cardboard box. The combined mass of child and box is ? = 120 kg. He climbs into box, which is initially at rest, at the top of the hill. The hill is inclined at an angle of 30 degrees with respect to the horizontal. The coefficients of static and kinetic friction between the box and the hill are mu s = 0.4 and mu k = 0.2. Consider that the box (with child inside) has begun to slide down the hill (you can assume that it has been given a brief push to get it started moving). What is the magnitude of the acceleration of the box? b. If the hill is 4 m tall, what is the child’s speed when he reaches the bottom? c. At the bottom of the hill, the ground becomes level (horizontal), but the coefficients of friction do not change. How far does the child slide before he comes to a stop? Thank you in advance, it's a lengthy question and I really need help :)
Two carts on a low friction air-track are connected by an unstretched spring. Cart 1 has an inertia of 1.5 kg while cart 2 has an inertia of 2.5 kg. The spring has a spring constant of 10 N/m and negligible inertia. You push cart 1 in the direction of the cart 2 with a constant force of 5.0 N. (a) What is the acceleration of the centre of mass of the cart-spring system? (b) What is the acceleration of each cart the instant you begin to push?
A small box with a weight of 35.0 N is placed on top of a larger box that has a weight of 80.0 N. The system of two boxes is at rest on a horizontal surface (the larger box is in contact with the surface). You apply an additional downward force of 30.0 N to the top of the small box by resting your hand on it. For this problem, use g = 10 N/kg. (a) What is the magnitude of the force exerted on the large box by the small box? (b) What is the magnitude of the force exerted on the large box by the surface? Now, imagine that the horizontal surface is the floor of an elevator, and the boxes are in the elevator, which has an acceleration directed downward of 1.00 m/s?.

A car of mass m₁ 1000 kg is connected to a trailer of mass m2 = 400 kg by a taut inextensible cable. The car's engine provides a constant forward driving force Fx = 7000 N, which causes the car-plus-trailer to accelerate forwards along the horizontal x-axis. The tension of the cable produces a force on the trailer and also a force on the car. You may assume that the magnitude of the two forces is the same. You may also ignore friction. What is the tension in the cable joining the car to the trailer? Give your answer by entering a number, correct to an appropriate number of significant figures, in the empty box below.
