Answer
$$W = 896{\text{ Joules}}$$
Work Step by Step
$$\eqalign{
& {\text{From the information we have:}} \cr
& F = {\text{112N }}\left( {{\text{force}}} \right) \cr
& D = 8{\text{m }}\left( {{\text{distance}}} \right) \cr
& {\text{Using the Definition of Work Done by a Constant Force}} \cr
& W = FD{\text{, Work}} = \left( {{\text{force}}} \right)\left( {{\text{distance}}} \right) \cr
& {\text{Substituting the known values}} \cr
& W = \left( {{\text{112N}}} \right)\left( {8{\text{m}}} \right) \cr
& W = 896{\text{Nm}} \cr
& W = 896{\text{Joules}} \cr} $$
