Introduction

In mathematics, solving for a variable in a formula is a crucial skill that helps us understand the relationship between different variables. In this article, we will focus on solving for s in the formula: $t^2 = 2p + as$ . This formula is commonly used in physics and engineering to describe the motion of an object. We will guide you through the step-by-step process of solving for s and provide you with the correct answer.

Understanding the Formula

The given formula is: $t^2 = 2p + as$ . This formula describes the relationship between the time (t), the distance (s), the acceleration (a), and the initial velocity (p). To solve for s, we need to isolate the variable s on one side of the equation.

Step 1: Isolate the Variable s

To isolate the variable s, we need to get rid of the terms that are not related to s. In this case, we need to get rid of the term $2p$ and the term $as$ . We can do this by subtracting $2p$ from both sides of the equation and then subtracting $as$ from both sides of the equation.

$t^2 - 2p = as$

Step 2: Factor Out the Common Term

Now that we have isolated the variable s, we can factor out the common term $a$ . We can do this by dividing both sides of the equation by $a$ .

$\frac{t^2 - 2p}{a} = s$

Step 3: Simplify the Equation

Now that we have factored out the common term $a$ , we can simplify the equation by combining the terms on the left-hand side.

$\frac{t^2 - 2p}{a} = s$

Conclusion

In conclusion, to solve for s in the formula: $t^2 = 2p + as$ , we need to isolate the variable s on one side of the equation. We can do this by subtracting $2p$ from both sides of the equation and then subtracting $as$ from both sides of the equation. We can then factor out the common term $a$ and simplify the equation. The correct answer is:

A. $\frac{t^2 - 2p}{a} = s$

Why is this the Correct Answer?

This is the correct answer because it satisfies the original equation. When we substitute the value of s into the original equation, we get:

$t^2 = 2p + a(\frac{t^2 - 2p}{a})$

Simplifying this equation, we get:

$t^2 = 2p + t^2 - 2p$

This equation is true for all values of t, p, and a. Therefore, the correct answer is:

A. $\frac{t^2 - 2p}{a} = s$
