The kinetic coefficient of friction between a body with mass ?1 = 8,00 ile and a surface on a slope ?1= 30.00 in a right triangular pattern given in the figure is 0.100. ?2 = 60.00 kinetic coefficient of friction between the mass of 2 = 7.00 moving on an inclined surface and the surface. The masses are tied together by a light rope passed through a frictionless reel as shown in the figure. For a mass of m2 = 7.00 ?? to have an acceleration of 0.380 ?⁄?2, a) What should be the tension in the rope because of the 7.00 ?? mass? b) What should be ?? between the mass of 7.00 ?? and the surface?

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?”
