Question

V²=u²+2as make u as the subject

​

Answer 1

u as the subject of the given formula is,
`u = \sqrt{v^(2)-2as }`

Explanation:

Given;

v² = u²+2as

To make u the subject of the formula, the following steps are taken;

v² = u²+2as

v² - 2as = u²

take the square - root of both sides of the equation;

`\sqrt{u^(2) } = \sqrt{v^(2)-2as } \\\\u = \sqrt{v^(2)-2as }`

Thus, u as the subject of the given formula is,
`u = \sqrt{v^(2)-2as }`
