A spring with a spring constant of 2.5 N/m is stretched by 2

Physics
1 answer:
mr_godi [17]3 years ago

Answer:

Eelas = 5 [J]

Explanation:

Elastic energy is associated with the ability that has a spring or any other material with elastic properties.

We can calculate the elastic energy by means of the following equation:

E_{elas}=\frac{1}{2} *k*x^{2}

where:

k = constant spring = 2.5 [N/m]

x = distance stretched = 2 [m]

E_{elas}=\frac{1}{2} *2.5*(2)^{2}\\E_{elas}=5[J]

kkurt [141]

The force is applied to the accelerating object that has a constant mass. Option A is correct.

<h3>What does Newton's second law of motion state?</h3>

The force applied to the object is the product of its mass and acceleration.

F = ma

Where,

F - force

m- mass

a - acceleration

From the equation, the force and the acceleration are in a proportional relation. The mass is not changing as given in the question.

Therefore, the force is applied to the accelerating object that has a constant mass.

In this problem, you will answer several questions that will help you better understand the moment of inertia, its properties, a
scoundrel [369]

Answer:

a)  Total mass form, density and axis of rotation location are  True

b)   I = m r²

Explanation:

a) The moment of inertia is the inertia of the rotational movement is defined as

       I = ∫ r² dm

Where r is the distance from the pivot point and m the difference in body mass

In general, mass is expressed through density

        ρ = m / V

        dm = ρ dV

From these two equations we can see that the moment of inertia depends on mass, density and distance

Let's examine the statements, the moment of inertia depends on

- Linear speed       False

- Acceleration angular False

-  Total mass form True

-  density True

- axis of rotation location   True

b) we calculate the moment of inertia of a particle

For a particle the mass is at a point whereby the integral is immediate, where the moment of inertia is

          I = m r²

Two bodies of mass m₁ &amp; m₂ are moving with the same velocity 'v' K.E. will be greater for??
boyakko [2]

Answer:

the one with a higher mass

Explanation:

The body with more mass will have the greater kinetic energy of the two.

Kinetic energy is the energy due to the motion of body. It is mathematically expressed as:

           K.E  = \frac{1}{2}  m v²

m is the mass

v is the velocity

 Since the velocity of the two bodies are the same, and mass is directly proportional to kinetic energy, the body with more mass will have a higher kinetic energy.

 So between mass m1 and mass m2, the one with a greater mass will have a higher kinetic energy
