An empty pail and a 34 kg wooden mass are tied together by a very light string which passes over a massless and frictionless pulley. There is a force of friction between the mass and the table and there is a coefficient of static friction of 0.76 and a coefficient of kinetic friction of 0.46. Water is added to the bucket one drop at a time until the system just begins to move. When the system just begins to move, what will the acceleration be? (Answer to 1 decimal place, use g = 9.8m/s2)
