Resolver x_{0}=v_{0}t+1/2gt^2

$$x _ { 0 } = v _ { 0 } t + \frac { 1 } { 2 } g t ^ { 2 }$$

Resolver g (complex solution)

$$\left\{\begin{matrix}g=-\frac{2\left(tv_{0}-x_{0}\right)}{t^{2}}\text{, }&t\neq 0\\g\in \mathrm{C}\text{, }&x_{0}=0\text{ and }t=0\end{matrix}\right.$$

Pasos para resolver unha ecuación lineal

Cambia de lado para que todos os termos variables estean no lado esquerdo.

$$v_{0}t+\frac{1}{2}gt^{2}=x_{0}$$

Resta v_{0}t en ambos lados.

$$\frac{1}{2}gt^{2}=x_{0}-v_{0}t$$

A ecuación está en forma estándar.

$$\frac{t^{2}}{2}g=x_{0}-tv_{0}$$

Divide ambos lados entre \frac{1}{2}t^{2}.

$$\frac{2\times \frac{t^{2}}{2}g}{t^{2}}=\frac{2\left(x_{0}-tv_{0}\right)}{t^{2}}$$

A división entre \frac{1}{2}t^{2} desfai a multiplicación por \frac{1}{2}t^{2}.

$$g=\frac{2\left(x_{0}-tv_{0}\right)}{t^{2}}$$

Resolver g

$$\left\{\begin{matrix}g=-\frac{2\left(tv_{0}-x_{0}\right)}{t^{2}}\text{, }&t\neq 0\\g\in \mathrm{R}\text{, }&x_{0}=0\text{ and }t=0\end{matrix}\right.$$
