Vf²=vi² + 2ad

A) solve for vi

B) solve for d

Using the same equation

A)

Vf² = vi² + 2ad Subtract 2ad from both sides

Vf² - 2ad = vi² Find the square roots of both sides

√ (Vf² - 2ad) = √ (vi²) Cancel out the squares with the square roots

Vf - √ (2ad) = vi Switch the sides to make it easier to read

vi = Vf - √ (2ad)

B) Vf² = vi² + 2ad Subtract vi² from both sides

Vf² - vi² = 2ad Divide both sides by 2a

(Vf² - vi²) / 2a = d Switch the sdies to make it easier to read

d = (Vf² - vi²) / 2a
