What is the total kinetic energy of a 0. 15 kg hockey puck sliding at 0. 5 m/s and rotating about its center at 8. 4 rad/s? the diameter of the hockey puck is 0. 076 m.

Answers

Answer 1

The mass of the puck is

m = 0.15 kg.

The diameter of the puck is 0.076 m, therefore its radius  is

r = 0.076/2 = 0.038 m

The sliding speed is

v = 0.5 m/s

The angular velocity is

ω = 8.4 rad/s

The rotational moment of inertia of the puck is

I = (mr²)/2

 = 0.5*(0.15 kg)*(0.038 m)²

 = 1.083 x 10⁻⁴ kg-m²

The kinetic energy of the puck is the sum of the translational and rotational kinetic energy.

The translational KE is

KE₁ = (1/2)*m*v²

      = 0.5*(0.15 kg)*(0.5 m/s)²

      = 0.0187 j

The rotational KE is

KE₂ = (1/2)*I*ω²

      = 0.5*(1.083 x 10⁻⁴ kg-m²)*(8.4 rad/s)²

      = 0.0038 J

The total KE is

KE = 0.0187 + 0.0038 = 0.0226 J

Answer: 0.0226 J

A small fair charges an admission fee for children and adults. The cost for admission is $3 per adult and $2 per child. On a certain day, total admission fees were $900, and 350 people attended the fair. How many children attended the fair that day? 80 children 150 children 200 children 320 children.

Answers

150 children attended the fair for that day if $900, and 350 people attended the fair, hence option b is correct.

What is the number of children attended the fair?

Detailed explanation:

Let's say there are x youngsters and y grownups.

350 persons in all visited the fair, thus.

So, x + y = 350.

In addition, fees per kid are $2 and fees per adult are $3.

Since, $900 is assumed to represent the entire sales.

So, 2x + 3y = 900

Consequently, we have the equation system,

2x + 3y = 900

x + y = 350

Now let's resolve the equations.

x + y = 350 ⇒ y = 350 - x

The result is that 2x + 3y = 900 2x + 3(350 -x) = 900 2x + 1050 - 3x = 900 -x = -150 x = 150.

The result is that y = 350 - x y = 350 - 150 y = 200.

Therefore, As a result, 150 children and 200 adults, respectively, visited the fair.

Evaluate the line integral, where c is the given curve. (x + 8y) dx + x2 dy, c c consists of line segments from (0, 0) to (8, 1) and from (8, 1) to (9, 0).

Answers

Parameterize the path from (0, 0) to (8, 1) by

• x(t) = 8t and y(t) = t

and the path from (8, 1) to (9, 0) by

• x(t) = 8 + t and y(t) = 1 - t

both with 0 ≤ t ≤ 1.

Over the first path, we have

[tex]\displaystyle \int_{C_1} (x+8y) \, dx + x^2 \, dy = \int_0^1 (8t + 8\cdot t) \cdot (8 \, dt) + (8t)^2 \cdot dt = \int_0^1 (128t + 64t^2) \, dt = \frac{256}3[/tex]

and over the second path,

[tex]\displaystyle \int_{C_2} (x+8y) \, dx + x^2 \, dy = \int_0^1 ((8 + t) + 8(1-t)) \cdot dt + (8+t)^2 \cdot (-dt) \\\\ = \int_0^1 (-48 - 23t - t^2) \, dt = -\frac{359}6[/tex]

and so the total line integral is

[tex]\displaystyle \int_C (x+8y) \, dx + x^2 \, dy = \frac{256}3 - \frac{359}6 = \boxed{\frac{51}2}[/tex]

Find the measure of a negative angle coterminal with 95°.

Answers

The measure of a negative angle coterminal with 95° are for any integer n 95° – (1,080n)°. Thus, option (b) is correct.

What is coterminal?

Angles in common position (angles with the starting side on the positive x-axis) that have a shared terminal side are referred to as coterminal angles. It's as easy as subtracting or adding 360° or 2 to each inclination, depending on whether it's measured in degrees or trigonometric functions. There are an endless amount of coterminal angles to be discovered.

The measure of a negative angle coterminal with 95°

Ф + 360 n

n is any integer (negative or positive)

Ф = 95°,

- 3n is an integer,

The co-terminal angles of 95° are,

= 95° + 360° (-3n)

= 95° - (1080 n)° ; for any integer n.

As a result, the measure of a negative angle coterminal with 95° are for any integer n 95° – (1,080n)°. Therefore, option (b) is correct.

What must be the value of x so that lines c and d are parallel lines cut by transversal p? 12 18 81 99.

Answers

Answer:18

Explanation:

The lines c and d are parallel if x = 18.

Hence, option B is correct.

Use the concept of an equation of line defined as:

A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.

In the figure,

The corresponding angles are (3x + 45)° and 81°

The objective is to find the value such that lines c and d become parallel.

Since we know that,

The sum of angles of parallel lines passing through a common line is 180°,

Therefore,

(3x + 45)° + 81° = 180°

Simplifying like terms,

3x = 54

Divide both sides by 3,

x = 18

Hence,

The required value of x is 18 which is option B.

You are going to write an essay about the life of a person whom you admire. Which two organizational aids could you use, and why?.

Answers

Answer:

Organizational aids are tools that allow an author to help the reader understand and follow the flow of information and ideas within a text. They provide a framework for organizing and connecting what has been written into a cohesive whole.

Explanation:

Two organizational aids that could be used to write about the life of someone whom you admire would either be chronological order or cause-and-effect. The chronological order might be used because the author may want to inform the reader about key events within the person's life, and this organizational aid would help to accomplish that goal. Using cause-and-effect could also work well because it could show how certain events were caused by other events, which ultimately led to the outcome of certain moments in the person's life.

Answer:

You can use a sequence chart or a timeline. Both organizational aids allow you to present the events of the person's life in order of occurrence.
