What are the formulas to find acceleration, velocity

Acceleration (a):

where

v0 = initial velocity (m/s)

v1 = final velocity (m/s)  

t = time taken (s)              

Alternative:

where

a = acceleration

v0 = initial velocity (m/s)

v1 = final velocity (m/s)

Velocity (v):

Velocity =

             =

Velocity=

v = velocity (m/s)

xf = the final position (m)

xi = the initial position (m)

t = the time in which the change occurs (s)

Δx =  the change in the position(m)
