Answer:
[tex]a=6000m/s^2[/tex]
Explanation:
To solve this problem we will use the equation for accelerated motion (which is the definition of acceleration):
[tex]a=\frac{v_f-v_i}{t}[/tex]
For our case we have a ball departing from rest, achieving a final velocity of 12m/s in a time equal to 2ms=0.002s, so substituting our values we have:
[tex]a=\frac{v_f-v_i}{t}=\frac{(12m/s)-(0m/s)}{(0.002s)}=6000m/s^2[/tex]
