           Work done  =  (weight) · (height)

                               =   (500 N) ·  (10 m)

                               =        5,000 joules

             Power  =  (work done)  /  (time to do the work)

                           =    (5,000 joules)  /  (10 s)

                           =        500 joules/sec

                           =        500 watts
