14. You are walking down the street when you see an enormous, 112 kg pickle rolling towards you at 12 m/s. A pickle of this size, let
alone the fact that it is rolling down the street of course, surprises you. You jump in front of it and begin pushing on it until you finally
bring it to a stop 27.4 seconds later. At this point you are arrested for interfering in the "World's Largest Pickle Rolling Championship".
Calculate the acceleration of the pickle.
