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

Two blocks, labeled D and E, are connected by an essentially massless string that runs over an essentially massless and frictionless pulley, as shown in Figure 2,
above. Block E hangs straight down and is initially moving downward with a speed of 3.82 meters per second. Block D is on an inclined plane, inclined at an
angle of theta = 0 = 28.6 degrees above horizontal. There is no friction between block D and most of the plane, but there is friction (with a coefficient of kinetic
friction equal to 0.49) between block D and a region of length L = 0.628 meters. Block D will slide over that region (and pass it completely) before it gets to the
end of the plane.
Block D has a mass of 0.74 kg, while block E has a mass of 0.98 kg. The only significant forces acting on the blocks are friction acting on block D (while in
contact with the region with friction), normal forces, tension forces, and gravity (with g = 9.81 m/s2).
Calculate the speed of block D (in units of meters per second) after it has slid a distance d = 1.14 meters up the plane (which will take it completely past the
region with friction).

An object of mass M is attached to a string. The length of the string is r and has no mass. The objects moves in a vertical circle counterclockwise as shown. When the ball is at point F, the string is horizontal. Point E is at the bottom of the circle and point Dis at the top of the circle. Air resistance is negligible. Express all algebraic answers in terms of the given quantities and fundamental constants. On the figures below, draw and label all the forces exerted on the ball when it is at points F and E, respectively.

With the string taut, the bead is at the point B, vertically below O, when it is set into vertical circular motion with an initial horizontal velocity u, as shown in the diagram. The string does not become slack in the subsequent motion. The velocity of the bead at the point A, where A is vertically above O, is v. (a) Show that v² = u² - 4ag.

Could you please answer the question in the image and this one below that follows the image. Question 5. The situation for this problem is as explained in question 4. Block E is moving up and to the left (and Block D is moving down). The mass of Block D is 3.8 kg. The mass of Block E is 2.9 kg. The coefficient of kinetic friction between Block E and the plane is 0.42. The inclined plane is inclined at an angle of θ = 24 degrees above horizontal.

For the purpose of this question, the acceleration is positive it points up and to the left (it is negative if it points down and to the right).
In the figure at the right is shown three graphs of the shapes of the same taut elastic string in three different circumstances, labeled A, B, and C. In some of the problems below, the string represents a guitar string, tied down at both ends, while in others, it is part of a very long telephone wire whose ends are not shown.

Two blocks are connected by a massless rope. The rope passes over an ideal (frictionless and massless) pulley such that one block with mass m1 = 12.25 kg is on a horizontal table and the other block with mass m2 = 7.5 kg hangs vertically. Both blocks experience gravity and the tension force, T. Use the coordinate system specified in the diagram. a.) Assuming friction forces are negligible, write an expression, using only the variables provided, for the acceleration that the block of mass m1 experiences in the x-direction. Your answer should involve the tension, T. b.) Under the same assumptions, write an expression for the acceleration, a2, the block of mass m2 experiences in the y-direction. Your answer should be in terms of the tension, T and m2. c.) Carefully consider how the accelerations a1 and a2 are related. Solve for the magnitude of the acceleration, a1, of the block of mass m1, in meters per square second. d.)Find the magnitude of the tension in the rope, T, in newtons.
