Integral de $$$\frac{a c \rho v^{2}}{2}$$$ em relação a $$$v$$$

Encontre $$$\int \frac{a c \rho v^{2}}{2}\, dv$$$.

Aplique a regra do múltiplo constante $$$\int c f{\left(v \right)}\, dv = c \int f{\left(v \right)}\, dv$$$ usando $$$c=\frac{a c \rho}{2}$$$ e $$$f{\left(v \right)} = v^{2}$$$:

$${\color{red}{\int{\frac{a c \rho v^{2}}{2} d v}}} = {\color{red}{\left(\frac{a c \rho \int{v^{2} d v}}{2}\right)}}$$

Aplique a regra da potência $$$\int v^{n}\, dv = \frac{v^{n + 1}}{n + 1}$$$ $$$\left(n \neq -1 \right)$$$ com $$$n=2$$$:

$$\frac{a c \rho {\color{red}{\int{v^{2} d v}}}}{2}=\frac{a c \rho {\color{red}{\frac{v^{1 + 2}}{1 + 2}}}}{2}=\frac{a c \rho {\color{red}{\left(\frac{v^{3}}{3}\right)}}}{2}$$

Portanto,

$$\int{\frac{a c \rho v^{2}}{2} d v} = \frac{a c \rho v^{3}}{6}$$

Adicione a constante de integração:

$$\int{\frac{a c \rho v^{2}}{2} d v} = \frac{a c \rho v^{3}}{6}+C$$

$$$\int \frac{a c \rho v^{2}}{2}\, dv = \frac{a c \rho v^{3}}{6} + C$$$A
