What should be the acceleration when a object is pushed by hand ?

  I presume that you are confused whether to take acceleration due to gravity (g=9.8m/s^2) or some other acceleration.
  
  Case 1: If the body on which you are applying force is moving along a horizontal direction, then the acceleration is calculated by the change in speed per unit time.
  a= (v-u)/(t2 - t1)
  v- final velocity of the body at time t2
  u - initial velocity of the body at time t1
  
  Case 2: If the body is moving in a vertical direction, then you will follow the same procedure and effective acceleration of the body is given by
  g' = g+a, if body is moving toward the earth
  g' = g-a, if body is moving away from the earth
