@marieeeee did they give you any more information for this question? 

$$a = \frac{ V _{2}-V _{1} }{ t _{2}-t_{1} }$$

anonymous · Answer

$$v=u+at$$
where v is your final velocity, u is initial velocity, t is time and a is acceleration
Other equations relating a and u are
$$s=ut+\frac{1}{2}at^2$$
$$v^2-u^2=2as$$
s is displacement

anonymous · Answer

You can clearly compare how acceleration changes when u is 0 or u has some value using any equation
