Using the information given, it's not possible to answer that question.

Regarding the cinder block, however . . .

                       Potential energy = (mass) x (gravity) x (height)

                                   8 joules  = (mass) x (9.8 m/s²) x (6 m)

                                 Mass = (8 J) / (9.8 m/s² x 6 m) = 0.136 kg .

             (A real cinderblock has about 67 times that much mass.)
