#1,5N# downwards

Explanation:

During the entire duration of its flight, the ball is a projectile and the only force acting on it is the force of gravitational attraction of the earth which remains constant at all times at #W=mg# directed vertically downwards.
(I assume that friction and other effects may be ignored for these purposes).
