Which has more momentum? A 60 kg object traveling at 3 m/s or a 9 kg object traveling at 23 m/s.

Answers

Answer 1

Answer:

If we compare 270 J and 2 380.5 J the higher is 2 380.5 J which is A 9 kg object traveling at 23 m/s

Explanation:

A 60 kg object traveling at 3 m/s

Given:

m = 60 kg

v = 3 m/s

Unknown:

KE or kinetic energy

Formula and solution:

KE = 1/2 mv²

KE = 1/2 (60kg) (3m/s)²

KE = (30kg) (9m²/s²)

Final Answer:

KE = 270 kg·m²/s² or simplify as 270 J

A 9 kg object traveling at 23 m/s

Given:

m = 9kg

v = 23m/s

Unknown:

KE or kinetic energy

Formula and solution:

KE = 1/2 mv²

KE = 1/2 (9kg) (23m/s)²

KE = (4.5kg) (529m²/s²)

Final Answer:

KE = 2 380.5 kg·m²/s² or simplify as 2 380.5 J

Answer 2
The 9 kg object has more momentum!
It has 207 Kg m/s compared to 180 Kg m/s of the 60 kg object.
Momentum = mass x velocity.

Consider a spring that does not obey Hooke's law very faithfully. One end of the spring is fixed. To keep the spring stretched or compressed an amount x, a force along the x-axis with x-component Fx=kx−bx2+cx3 must be applied to the free end. Here k=100N/m, b=700N/m2, and c=12000N/m3. Note that x>0 when the spring is stretched and x<0 when it is compressed.

Answers

Answer:

The work done will be 0.115 J.

Explanation:

Given that,

[tex]k=100\ N/m[/tex]

[tex]b=700\ N/m^2[/tex]

[tex]c=12000\ N/m^3[/tex]

A force along the x-axis with x-component,

[tex]F(x)=kx-bx^2+cx^3[/tex]

Suppose, How much work must be done to stretch this spring by 0.050 m from its unstretched length?

We need to calculate the work done

Using formula of work done

[tex]W(x)=\int{F(x)dx}[/tex]

Put the value into the formula

[tex]W(x)=\int{(kx-bx^2+cx^3)dx}[/tex]

[tex]W(x)=\dfrac{kx^2}{2}-\dfrac{bx^3}{3}+\dfrac{cx^4}{4}[/tex]

Put the value of k,b,c and x

[tex]W(0.050)=\dfrac{100\times(0.050)^2}{2}-\dfrac{700\times(0.050)^3}{3}+\dfrac{12000\times(0.050)^4}{4}[/tex]

[tex]W(0.050)=0.115\ J[/tex]

Hence, The work done will be 0.115 J.

The value of spring displacement is greater than zero. Therefore, spring is stretched.

Force in spring :

  It is given as,  [tex]F=kx[/tex]

Where k is constant and x is amount of displacement.

The force function is given that,

       [tex]F(x)=kx-bx^{2}+cx^{3}[/tex]

Here given that,  [tex]k=100N/m, b=700N/m^{2} , c=12000N/m^{3} .[/tex]

Substitute all values in above equation,

           [tex]F(x)=100x-700x^{2} +12000x^{3}[/tex]

To check, the spring is stretched or it is compressed.

Substitute f(x) = 0

          We get x is greater than zero.

Thus, The value of spring displacement is greater than zero. Therefore, spring is stretched.

non-foliated igneous rock


foliated igneous rock

Answers

Answer:

metamorphic rock

Explanation:

Igneous rocks can be changed into metamorphic rocks when heat and pressure are applied to the rock.

Pressure and heat in the presence of a fluid phase cause metamorphic transformation of a prolith.

At the right temperature and pressure, an igneous rock will not form magma but will undergo mineralogical changes to form metamorphic rocks. These changed rocks have different mineral facies that are different from those of the prolith.

Through heat and pressure, igneous rocks can be transformed into metamorphic rocks.

how far will a 600 kg boat travel in 12 s if there is a constant 900 N force on it and it starts from rest?​

Answers

Answer:

Distance, S = 108 meters.

Explanation:

Force is given by the multiplication of mass and acceleration.

Mathematically, Force is;

[tex] F = ma[/tex] ............equation 1

Where;

F represents force measured in Newton. m represents the mass of an object measured in kilograms. a represents acceleration measured in meters per seconds square.

Given the following data;

Since the boat is starting from rest, initial velocity, u = 0

Mass, m = 600kg

Time, t = 12s

Force, F = 900N

Substituting into equation 1, we have;

[tex] 900 = 600*a[/tex]

[tex]a = \frac{900}{600}[/tex]

Acceleration, a = 1.5 m/s²

T

To solve for distance, we would use the second equation of motion;

[tex] S = ut + \frac {1}{2}at^{2}[/tex]

Substituting the values into the equation, we have;

[tex] S = 0(12) + \frac {1}{2}*1.5* 12^{2}[/tex]

[tex] S = 0 + 0.75* 144[/tex]

Distance, S = 108m

Therefore, the distance covered by the boat is 108 meters.

Explanation:

Any reaction in which energy is absorbed is said to be endothermic. Hence, option B is correct, but the rest are not correct.

What is an Endothermic Reaction?

In every chemical process, energy is involved. When new bonds form in products, energy is produced. Reactant bonds are broken using energy. Exothermic reactions are those that produce more energy when new bonds form in the products than is needed to break existing bonds in the reactants.

In contrast, endothermic reactions are the opposite. Endothermic reactions release more energy when new bonds form in the products than is required to break bonds in the reactants.

During the reaction, a large amount of energy is absorbed.

T.J. Berry, R-Kearney, says his billHB 224isnt a cure-all by any stretch. But legalizing ads inside and outside the buses would give school districts one additional way to raise money in these tough times.3 Every single school district has had to deal with budget concerns, Berry said last week. And generally speaking, the way they have had to deal with those has been cuts or tax increases.4 The school bus is something that is already out there and paid for, he said. His bill would permit districts to generate a modest stream of income from their buses.5 Few question the need for finding additional funds when it comes to educating children, but at least two groups think the school bus exteriors should remain ad-free.6 There is no such thing as free money, said Josh Golin, associate director for the Campaign for a Commercial Free Childhood. There are real costs to this: the price of selling out your students to advertisers.7 Students dont need the first and last message they receive from their schools each day to be advertisements, Golin said. Students boarding a bus are certainly a captive audience.8 The National Association of State Directors of Pupil Transportation Services opposes advertising on safety grounds. Obscuring the recognizable school-bus yellow exterior with ads and distracting other drivers present a safety problem around school buses that cannot be ignored, the group said in its position paper.9 National studies have shown that anything that diverts a drivers attention from the road can pose a hazard, opponents say.10 And a big yellow bus doesnt distract? Berry asked.11 Several years ago in Indiana, a Department of Education lawyer suggested that allowing advertisements on buses would invite First Amendment challenges by spurned advertisers, the group noted.12 Berry said the bill would limit the types of advertising that would be allowed.13 The regulations would prohibit ads that contain obscene or sexual material, or messages associated with gambling, tobacco products, alcohol, and political campaigns or causes. The ads could not promote drug use or any illegal activity or antisocial behavior. They cant contain harmful, discriminatory, false, misleading or deceptive messages.14 There are a lot of safeguards being built in, he said.15 Berry emphasized that the space reserved for the ads would be very limited, meaning toward the back of the bus.16 By 2012, nine statesArizona, Colorado, Massachusetts, Nevada, New Jersey, New Mexico, Tennessee, Texas and Utahpermitted advertising on the exterior of school buses, according to the Campaign for a Commercial-Free Childhood. Several, including Missouri, considered it last year.17 The bill made it out of the Missouri House last year but did not clear the Senate, Berry said.
