For the graph of F/a (in y-axis) versus the total cart mass (in x-axis), what slope (value) would you expect, and why? What is the unit of the slope? Compare the value you obtained to the expected value.

In this diagram, what direction would the force go in? The textbook says the force goes to the left but shouldn't it go into the paper?

A cabinet of mass 3.7 kg is at rest on a ramp as shown. What is the magnitude of the friction force on the cabinet, in Newtons? The coefficients of friction between the cabinet and ramp are Ps = 0.850 and uk = 0.750. Use g = 10 m/s2. (Hint: what type of friction is it?) Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. 30.0

Drag force is an important concept in automobile design. It is modeled as Fa = 0.5PVAC4 where Fa = drag force [lb] air density [slugs/ft³] V = speed of vehicle [ft/s] A = frontal area of car [ft2] Cả = drag coefficient [?] What must be the units for Ca? Show all steps. Break down into fundamental dimensions. Ed

please ensure this question is 100% correct, thanks. Forces of 10 N and 27 N act on an object. The angle between the two forces is 56 degrees. Find the resultant force on the object and the equilibrant of the two forces. Give direction relative to the 10 N force. Include a vector diagram with your solution.

Fill in the data as you complete the lab. In the table, m represents mass and r represents the distance from the fulcrum. Use a zero or a dash (–) when there is no second object on one side of a problem. Include units with all data. The image of the balancing act is scenario 2.  The object on the right is called Mystery A.

The previous step focused on friction for horizontal surfaces. As we discussed above, angled surfaces like the wedge below have different considerations. FN = mg cos(0) F₁ = mg F₁ = ? F₁ = ? Fy=mg cos(0) Specifically, we have the following considerations. 1. The normal force is not equal to mg. 2. There is a force acting along the angle of the wedge due to gravity. What is the coefficient of static friction ? Fx = mg sin(0) Let's consider the implications of this type of problem with the following examples. For all of the examples, the box has a mass of 25 kg. Imagine the box is on a surface that allows you to adjust the incline angle, 0. You find the maximum angle where the box remains stationary. That is, at any higher angle, and the box begins to slide. The static friction force at this maximum angle is 150 N. What is the angle 0 (in degrees)? Now you raise the incline to an angle of 60° greater than the angle of maximum static friction found above. At this angle, the box slides…

You push a block along the ice, as shown below.  Which of these could be the net force equations in the x and y directions?  Use the convention that N is the normal force, f is the frictional force, Fg is the force of gravity, and Fapp is the force you apply.

A man pulls a crate with a rope. The crate slides along the floor in the horizontal direction (x direction). The man exerts a force of 50 N on the rope, and the rope is at an angle 0. Described how the force components (Fx,Fy) change as the angle increases from 0 degrees to 90 degrees and use your graph to explain your answer. Give a detailed explanation of the forces at 0= 0, 45degrees, and 90 degrees. please show a sample calculation at one angle for both components.
