Deceleration Formula:
Deceleration is the opposite of acceleration. It is the rate at which an object slows down. Deceleration is the final velocity minus the initial velocity, with a negative sign in the result because the velocity is dropping.
The formula is given as
deceleration = (final velocity - initial velocity) / time
d = (vf - vi)/t
d = deceleration
vf = final velocity
vi = initial velocity
t = time
Let value of vf = f and value of vi=i
