V²=u²+2as make u as the subject

u as the subject of the given formula is,

Step-by-step 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;

Thus, u as the subject of the given formula is,
