Calculations: Notice that your data consists of times (t) and distances (x). In order to calculate acceleration you must use the four equations of motion. First work with Equation 2:                         Equation 2:      x = (v/2)t

Rewriting to isolate v, the equation becomes:
Equation 2:      v= (2x)/t
You already know the distance, x and the time, t. Now you can solve for velocity, v, by using Equation 2 in this form. Fill in v for each trial on your data sheet. Use Equation 1 to find acceleration, but first it must be rewritten to isolate the variable (a).

Equation 1:      v=at        divide both sides of the equation by (t):                  a= v/t

With Equation 1 rewritten in this way it is easy to solve for acceleration, a using time, t from your data sheet and velocity, v that you already calculated....
