The final velocity V is given by the equation:
i
V = V + at
. f .... i
Where V is the objects initial velocity
i
a, as it's accelleration
and t is the durationof the accelleration
a= ?

your question is not clear at all.
what is what you want????
what is f...i?
what is i?
and why do you have v=v+at?
this does not make sense, unless a=0 or t=0

You will have to plug in numbers.
Let's say that initial velocity is 25 mph westbound.
(Velocity is a vector so it needs direction)
After 6 minutes (.1 hrs), it's new velocity is 50 mph westbound.
Remember, acceleration is change in velocity over time, so units will be velocity units / time units.
So, V(f) = V(i)+at
50 mph = 25 mph + a(.1hrs)
Solve for a:
(50 mph - 25 mph) / .1 hrs = a
(25 miles / hr) / (.1 hrs) = a
250 mi/hr/hr = a

v0=initial velocity
v1=final velocity
so
v1=v0+at
next, you must subtract v0 from both sides and then divide both sides by time (t)
then you get
(v1-v0)/t=a
then you plug in the information you have and solve for the acceleration.

a is the acceleration due to gravity and is equal to 32 ft/sec2

v=u+at
therefore a=(v-u)/t
Is this what you meant?

a=(v-u) /t
we use u instead of vi
