Gravity causes a falling object to fall 9.8 m/s faster every second it falls.

Kenny's book started out with no speed when it was dropped. 
1.5 sec later, it was falling at (9.8 x 1.5) = 14.7 m/s .

During the fall, its average speed was  1/2(0 + 14.7) = 7.35 m/s .

Distance it covered = (average speed) x (time) =

                                             (7.35 m/s) x (1.5 sec) = 11.025 m
