Question

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.

Which is an equivalent equation solved for t?

t = t equals StartFraction f minus v Over a EndFraction z.
t = t equals StartFraction f minus a Over v EndFraction z.
t = a(f – v)
t = v(f – a)

Answer 1

Solve f = v + at for t:

Subtract v: at = f − v.
Divide by a: t = (f − v) / a.

So the correct choice is the first one: t = (f − v) / a.
