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 a?

StartFraction f minus v Over t EndFraction equals a. = a
StartFraction f Over t EndFraction plus v equals a.– v = a
StartFraction f plus v Over t EndFraction equals a. = a
StartFraction f Over t EndFraction plus v equals a.+ v = a

Answer 1

Solve f = v + a t for a:

Subtract v: f − v = a t
Divide by t (t ≠ 0): a = (f − v)/t

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