A ball rolls over the edge of a table with a horizontal velocity, v. The height of the table is 1.6m and the horizontal range of the ball from the base of the table is 20m. What is the magnitude and direction of the ball's acceleration right after it leaves the table?

neither accurate nor precise.

does anyone know or what?

answer;
