Friction: a 50-kg box is resting on a horizontal floor. A force of 250 n directed at an angle of 30. 0° below the horizontal is
sergejj [24]

The net forces on the box parallel and perpendicular to the surface, respectively, are

∑ F[para] = (250 N) cos(-30.0°) - F[friction] = (50 kg) a

and

∑ F[perp] = F[normal] + (250 N) sin(-30.0°) - F[weight] = 0

where a is the acceleration of the box. (We ultimately don't care what this acceleration is, though.)

To decide whether the friction here is static or kinetic, consider that when the box is at rest, the net force perpendicular to the floor is

∑ F[perp] = F[normal] - F[weight] = 0

so that, while at rest,

F[normal] = (50 kg) g = 490 N

Then with µ[s] = 0.40, the maximum magnitude of static friction would be

F[s. friction] = 0.40 (490 N) = 196 N

so that the box will begin to slide if it's pushed by a force larger than this.

The horizontal component of our pushing force is

(250 N) cos(-30.0°) ≈ 217 N

so the box will move in our case, and we will have kinetic friction with µ[k] = 0.30.

Solve the ∑ F[perp] = 0 equation for F[normal] :

F[normal] + (250 N) sin(-30.0°) - F[weight] = 0

F[normal] - 125 N - 490 N = 0

F[normal] = 615 N

Then the kinetic friction felt by the box has magnitude

F[k. friction] = 0.30 (615 N) = 184.5 N ≈ 185 N

Find the total area of the solid figure. 78 sq. in. 90 sq. in. 60 sq. in.
yaroslaw [1]

The total area of the figure will be 245 sq. in.

<h3>Total area of a cylinder</h3>

The figure is a cylinder and the total area of a cylinder is given by the formula below:

Total Area of a cylinder = 2πrh+2πr^2

Where r is the radius, h is the height of the cylinder, and π is constant with a value of 22/7.

In this case, looking at the image, the radius is 3" while the height is 10". Substituting these values into the formula above, we have:

Total Area = 22/7((2x3x10) + (2x3^2)) = 22/7(60+18)

           = 245 sq. in.

Thus, the total area of the solid figure is 245 sq. in.

In a recent survey, 1358 arizona state university students were asked about their plans after graduation. The following results
lisov135 [29]

The answers to the given questions on the survey of students by the use of a Venn Diagram are;

A) Venn diagram attached

B) 57 Students

C) 811 Students

D) 785 Students

E) 67 Students

<h3>Understanding Venn Diagrams</h3>

We are given;

  • Total number of Students = 1358
  • Number of Students that plan to get a new job = 1194
  • Number of Students that plan to attend graduate school = 306
  • Number of Students that plan to buy a new car = 547
  • Number of Students that plan to do all three things = 46
  • Number of Students that plan to only attend graduate school = 28
  • Number of Students that plan to get a job and buy a new car, but not attend graduate school = 432
  • Number of Students that plan to get a new job and attend graduate school = 221

A) I have drawn a Venn Diagram to depict this given numbers of students and I have attached it.

B) From the venn diagram, we can see that the number of people that plan to attend graduate school and buy a new car, but not get a new job = 57

C) From the Venn diagram, we can calculate the number of students that do not plan to buy a new car is;

541 + 175 + 28 + 67 = 811

D) From the venn diagram, we can calculate the number of students plan to get a new job or buy a new car as;

541 + 175 + 12 + 57 = 785

E) From the venn diagram, we can see that the number of students that do not plan to get a new job, attend graduate school, nor buy a new car is; 67

The complete part of the question is;

A) Draw a Venn diagram that represents the situation consisting of 2. cardinalities.

B) How many people plan to attend graduate school and buy a new car, but not get a new job?

C) How many students do not plan a buy a new car?

D) How many students plan to get a new job or buy a new car?

E) How many students do not plan to get a new job, attend graduate school, nor buy a new car?
