For constant acceleration problems use one or more of the following equations, as appropriate:

 

v = u + at

v2 = u2 + 2as 

s = ut + (1/2)at2

 

where u = initial velocity, v = final velocity, a = acceleration, t = time taken, s = distance travelled.

First one:  vf = vo + at        (velocity final = velocity original + accel * t)        vf =6.6 m/s      vo = 0  

     then use   xf = x+ v * t         x= final position   xo = original position (0)

 

Second one : xf = x0 + vot + 1/2 at^2    to find a

    then  use  vf = v+ a t   to find  vf
