Question

The formula to determine energy is uppercase E = one-half m v squared. What is the formula solved for v?

Answer 1

d

Explanation:

Answer 2

Explanation:

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

All the variables on the right are being multiplied together then the whole mess is being divided by 2. Let's get rid of the 2 first. The undoing of division is multiplication, so we will begin by multiplying both sides by 2 to get

`2E=mv^2`

Next we will move the m. The undoing of multiplication is division. So we divide both sides by m to get

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

The undoing of a square is to take the square root, so we will do that to both sides giving us, finally

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