CorrectThe total mechanical energy of an object with mass mat height in a closed system can be written as ME v the velocity of the object in terms of the given class=

Respuesta :

To solve the given equation for v, isolate the variable to one side of the equal sign, this way:

[tex]\begin{gathered} ME=\frac{1}{2}mv^2+mgh \\ ME-mgh=\frac{1}{2}mv^2 \\ \frac{2}{m}(ME-mgh)=v^2 \\ \frac{2}{m}ME-2gh=v^2 \\ v=\sqrt[]{\frac{2}{m}ME-2gh} \end{gathered}[/tex]
