Question

Make V the subject of the formula E=mv2/2

Answer 1

Answer:

v = ± $\sqrt{\frac{2E}{m} }$

Step-by-step explanation:

Given

E = $\frac{mv^2}{2}$ ( multiply both sides by 2 to clear the fraction )

2E = mv² ( divide both sides by m )

$\frac{2E}{m}$ = v² ( take the square root of both sides )

v = ± $\sqrt{\frac{2E}{m} }$
