Question

E = MV^2 ÷ 2 + mgh, Make V Subject of the formula​

Answer 1

`\red{ \bold{ V = \sqrt{(2(E - mgh))/(M)}}}`

Explanation:

`E = MV^2 ÷ 2 + mgh \\ \\ E - mgh = MV^2 ÷ 2 \\ \\ 2(E - mgh)= MV^2 \\ \\ (2(E - mgh))/(M)=V^2 \\ \\ \sqrt{(2(E - mgh))/(M)} = V \\ \\ \red{ \bold{ V = \sqrt{(2(E - mgh))/(M)}}}`
