One of the most popular kinematic equations is the one for final velocity: vf = vi + a*t, where vf = final velocity, vi = initial velocity, a = acceleration and t = time. Write a method that calculates this formula given the arguments. Then in your main, ask the user to input the initial velocity and acceleration for 2 items. Finally, output their increasing velocities over 10 timesteps, calling your method in each iteration. Example Output: Enter the initial...
