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?”

A person with mass m1 = 59 kg stands at the left end of a uniform beam with mass m2 = 106 kg and a length L = 3.4 m. Another person with mass m3 = 53 kg stands on the far right end of the beam and holds a medicine ball with mass m4 = 12 kg (assume that the medicine ball is at the far right end of the beam as well). Let the origin of our coordinate system be the left end of the original position of the beam as shown in the drawing. Assume there is no friction between the beam and floor. 1) What is the new x-position of the person at the left end of the beam? (How far did the beam move when the ball was throw from person to person?) 2) To return the medicine ball to the other person, both people walk to the center of the beam. At what x-position do they end up?
A block with mass m1 hangs from a rope that is extended over an ideal pulley and attached to a second block with mass m2 that sits on a ledge. The second block is also connected to a third block with mass m3 by a second rope that hangs over a second ideal pulley as shown in the figure below. If the friction between the ledge and the second block is negligible,m1 = 2.00 kg, m2 = 5.80 kg,and m3 = 8.20 kg, find the magnitude of the tension in each rope and the acceleration of each block. (Enter the magnitude.) a=?m/s^2. T12=?N.T23=?N.
Displayed to the right are two carts connected by a cord that passes over a small frictionless pulley. Each cart rolls freely with negligible friction. Consider the mass of the cart to be m1 = 18.1 kg and the angle the first cart sits on to be θ1 = 37.5°, while the mass of the second cart as m2 = 24.1 kg and the angle it sits on to be θ2 = 50.5°.a = 1.759m/s^2 What is the equation for tension in regards to the rope coming from the second block? Answer in terms of the mass of the block m2, the acceleration due to gravity g, the angle θ2, and the acceleration of the blocks found previously a. Calculate the tension in the rope T in newtons.
Find the center of mass coordinates XCM y YCM of the arrangement of masses shown. Assume that the connecting bars are massless. (m= 3.0 kg; M = 1.5 kg; L = 2.0 m)
Which one of the following statement is true: a. The center of mass of an object must lie within the object. b. The center of mass of an object cannot move if the net force exerted on the object is zero. c. All the mass of an object is actually concentrated at its center of mass. d. The center of mass of an object must lie outside the object. e. None of the above. ANS: e Can someone please explain why they're false. I know that the CofM can be outside the object or inside so I know a and d are false. I know, for instance, with a baseball bat that the hitting end is more massive and that the CofM is more towards the more massive object so I can assume that c is false. I'm not sure about b. Thanks
