Final answer:
To solve for initial velocity Vi in the formula Vf = Vi + at, subtract the product of acceleration (a) and time (t) from the final velocity (Vf): Vi = Vf - at.
Step-by-step explanation:
To rewrite the formula Vf = Vi + at to solve for initial velocity Vi, you need to manipulate the equation. First, you want to isolate Vi on one side of the equation. You can achieve this by subtracting the product of acceleration (a) and time (t) from both sides of the equation. So, the rewritten formula to solve for Vi becomes:
Vi = Vf - at
Let's break down the process:
-
Using this equation, you can determine the initial velocity if the final velocity, acceleration, and time are known.
