Change the formula to make u the subject of v²=u²+2ad
3 answers
u = √(v² - 2ad)
Show working out
Starting with the equation:
v² = u² + 2ad
Subtracting u² from both sides:
v² - u² = 2ad
Rearranging the equation to solve for u:
u² = v² - 2ad
u = √(v² - 2ad)
Therefore, the correct formula with u as the subject is u = √(v² - 2ad).
v² = u² + 2ad
Subtracting u² from both sides:
v² - u² = 2ad
Rearranging the equation to solve for u:
u² = v² - 2ad
u = √(v² - 2ad)
Therefore, the correct formula with u as the subject is u = √(v² - 2ad).
