Question

The formula to determine energy is E=1/2mv2? What is the formula solved for v?​

Answer 1

v = √(
`(2E)/(m)` )

Explanation:

E=1/2mv²

v² = (
`(2E)/(m)` )

v = √(
`(2E)/(m)` )

Answer 2

`v=\sqrt{(2E)/(m)}`

Explanation:

`E= (1)/(2) mv^2`

Solve the equation for v

To remove fraction , multiply both sides by 2

`2 \cdot E= (1)/(2) mv^2 \cdot 2`

`2E=mv^2`

Divide both sides by 'm' to isolate v^2

`(2E)/(m)=v^2`

Now to remove square from V, we take square root on both sides

`\sqrt{(2E)/(m)} =v`

`v=\sqrt{(2E)/(m)}`
