Introduction

In physics, the position of a particle is often described by a function of time, known as the position function. This function, denoted by s(t)s(t), gives the position of the particle at time tt. In this article, we will explore the position function of a particle moving along a coordinate line, and use it to find the particle's velocity at a given time.

The Position Function

The position function of the particle is given by s(t)=2+2πs(t) = \sqrt{2+2 \pi}. This function describes the position of the particle at time tt, and is measured in meters.

Understanding the Position Function

To understand the position function, let's break it down into its components. The function s(t)=2+2πs(t) = \sqrt{2+2 \pi} is a square root function, which means that it takes the square root of the expression inside the parentheses. In this case, the expression inside the parentheses is 2+2π2+2 \pi.

The Meaning of the Position Function

The position function s(t)=2+2πs(t) = \sqrt{2+2 \pi} tells us that the position of the particle at time tt is equal to the square root of 2+2π2+2 \pi. This means that the position of the particle is constantly changing, and is dependent on the time tt.

Finding the Velocity

To find the velocity of the particle, we need to take the derivative of the position function with respect to time. The derivative of a function f(t)f(t) is denoted by f(t)f'(t), and represents the rate of change of the function with respect to time.

The Derivative of the Position Function

To find the derivative of the position function s(t)=2+2πs(t) = \sqrt{2+2 \pi}, we can use the chain rule. The chain rule states that if we have a composite function of the form f(g(t))f(g(t)), then the derivative of the composite function is given by f(g(t))g(t)f'(g(t)) \cdot g'(t).

Applying the Chain Rule

In this case, we have s(t)=2+2πs(t) = \sqrt{2+2 \pi}. We can rewrite this as s(t)=(2+2π)1/2s(t) = (2+2 \pi)^{1/2}. Now, we can apply the chain rule to find the derivative of s(t)s(t).

The Derivative of s(t)s(t)

Using the chain rule, we have:

s(t)=ddt(2+2π)1/2=12(2+2π)1/2ddt(2+2π)s'(t) = \frac{d}{dt} (2+2 \pi)^{1/2} = \frac{1}{2} (2+2 \pi)^{-1/2} \cdot \frac{d}{dt} (2+2 \pi)

Simplifying the Derivative

Now, we can simplify the derivative of s(t)s(t).

s(t)=12(2+2π)1/20=0s'(t) = \frac{1}{2} (2+2 \pi)^{-1/2} \cdot 0 = 0

The Velocity of the Particle

The derivative of the position function s(t)s(t) is equal to the velocity of the particle. Therefore, the velocity of the particle is given by s(t)=0s'(t) = 0.

Conclusion

In this article, we have explored the position function of a particle moving along a coordinate line, and used it to find the particle's velocity at a given time. We have shown that the velocity of the particle is given by the derivative of the position function, and have found that the velocity of the particle is equal to zero.

Final Answer

The final answer is 0\boxed{0}.

Discussion

The position function s(t)=2+2πs(t) = \sqrt{2+2 \pi} describes the position of a particle at time tt. The derivative of this function, s(t)s'(t), represents the velocity of the particle. In this case, we have found that the velocity of the particle is equal to zero.

Why is the Velocity Zero?

The velocity of the particle is zero because the position function s(t)=2+2πs(t) = \sqrt{2+2 \pi} is a constant function. This means that the position of the particle does not change with time, and therefore the velocity of the particle is zero.

What is the Physical Meaning of Zero Velocity?

A velocity of zero means that the particle is not moving. In other words, the particle is at rest.
