Answer:
t = (f - v)/a
Explanation:
We have been given that;
The equation f = v + at represents the final velocity of an object, f, with an initial velocity, v, and an acceleration rate, a, over time, t.
The question requires us to solve for t;
The first step is to subtract v on both sides of the equation,
f - v = v + at - v
f - v = at
The next step is to divide both sides by a,
(f - v)/a = t
which is our required equation solved for t.
