Answer:
The x-t graph drawn by khytij garg is correct but I don't agree with the a-t graph drawn by him. According to me, since the direction of the gravitational acceleration always remains downwards no matter what the motion of the object is, therefore along with magnitude, the direction will also remain constant, i.e. downwards. Therefore, since vertically downward direction is taken as positive, the graph should be a straight line with slope=0 and positive, from t=0 to t=2t0.
