The work required to strecth the spring is about 2.0 Joules

\texttt{ }

<h3>Further explanation</h3>

Let's recall Elastic Potential Energy formula as follows:

\boxed{E_p = \frac{1}{2}k x^2}

<em>where:</em>

<em>Ep = elastic potential energy ( J )</em>

<em>k = spring constant ( N/m )</em>

<em>x = spring extension ( compression ) ( m )</em>

Let us now tackle the problem!

\texttt{ }

<u>Given:</u>

spring constant = k = 2500 N/m

extension = x = 4.00 cm = 4.00 × 10⁻² m

<u>Asked:</u>

work required = W = ?

<u>Solution:</u>

<em>We will calculate the </em><em>work</em><em> required to stretch the spring as follows:</em>

W = E_p

W = \frac{1}{2} k x^2

W = \frac{1}{2} \times 2500 \times ( 4.00 \times 10^{-2} )^2

W = 1250 \times ( 16.00 \times 10^{-4} )

W = 20000 \times 10^{-4}

W = 2.0 \times 10^4 \times 10^{-4}

W = 2.0 \texttt{ J}

\texttt{ }

<h3>Conclusion:</h3>

The work required to strecth the spring is about 2.0 Joules

W = 1/2k*x^2.

k = spring constant = 2500 n/m.
x = distance = 4 cm = 0.04m (convert to same units).

W = 1/2(2500)(0.04)^2 = 2J.

When the spring, with the attached 275.0 g mass, is displaced from its new equilibrium position, it undergoes SHM. Calculate the
topjm [15]

Answer:

The period of oscillation is 1.33 sec.

Explanation:

Given that,

Mass = 275.0 g

Suppose value of spring constant is 6.2 N/m.

We need to calculate the angular frequency

Using formula of angular frequency

\omega=\sqrt{\dfrac{k}{m}}

Where, m = mass

k = spring constant

Put the value into the formula

\omega=\sqrt{\dfrac{6.2}{275.0\times10^{-3}}}

\omega=4.74\ rad/s

We need to calculate the period of oscillation,

Using formula of time period

T=\dfrac{2\pi}{\omega}

Put the value into the formula

T=\dfrac{2\pi}{4.74}

T=1.33\ sec

Hence, The period of oscillation is 1.33 sec.

At what distance between two objects would you have the greatest gravitational force
Alla [95]

The gravitational force is inversely proportional to the
square of the distance between their centers.  So the
force is greatest when the distance is zero.
