Kinematics

There is already a kinematics calculator just not for all the formulas of kinematics. I was wondering if you could implement a calculator for the following equations of kinematics:
d= (Vi t) + (.5 a (t^2))
Vf=Vi + (a t)
Vf^2= (Vi^2) + (2 a d)
d= ((Vi + Vf)/2) * t

Where:
Vi= Velocity Initial in meters per second
Vf= Velocity Final in meters per second
d= Displacement in meters
a= Acceleration in meters per second squared
t= Time in seconds
