Acceleration is defined as the change in velocity in a given time.

It is given by:

$\overline{)\begin{array}{rcl}{\mathbf{a}}& {\mathbf{=}}& \frac{\mathbf{∆}\mathbf{v}}{\mathbf{t}}\\ & {\mathbf{=}}& \frac{{\mathbf{v}}_{\mathbf{f}}\mathbf{-}{\mathbf{v}}_{\mathbf{0}}}{\mathbf{t}}\end{array}}$, where a is acceleration, vf is the final velocity, v0 is the initial velocity, and t is time.

Let's now calculate acceleration for the four cars.
