A ladder is propped up against a wall. At the instant when the top of the ladder, point A, is 4 m above the floor, the lower end of the ladder, point B, is 3 m from the wall. If the base of the ladder, point B, at this moment is sliding out at a speed of 2 m/s, what is the speed (absolute magnitude of the velocity) of the top of the ladder, point A, in m/s? Round to the first decimal. Take g to be 10 m/s².
