Final answer:
To find x, first, identify the unknown and the known variables, then choose the appropriate equation. For a quadratic equation, apply the quadratic formula to get potential values of x, and use the context to determine the feasible solution, as in this example, where x equals 0.00139.
Step-by-step explanation:
The process of finding x involves a few systematic steps. First, it is important to identify the unknown, which is x in this case. Then, we move to identify the knowns, which involves recognizing the given values for all other variables in the problem.
To efficiently find x, we choose the most suitable equation. As mentioned, we have one that fits perfectly as it involves only one unknown, which significantly reduces complexity. The equation, x = xo + Ut, is optimal as every variable other than x is known. We can proceed to solve this equation by plugging in the known values and performing algebraic manipulations to isolate x.
In scenarios where a quadratic equation is applicable, we would apply the quadratic formula. In this particular case, solving the quadratic equation gives us two possible values for x: -0.0024 and 0.00139. Since negative results do not apply to our real-world context, we conclude that x equals 0.00139.
