Given:  Weight  W = 100 lbs  convert to Kg = 45.36 Kg

             Height h = 8 Ft  convert to meter = 2.44 m

             Time t =10 s

Required: Power output

Formula: P = W/t       Work = Force x distance  or  Work = mgh

               P = mgh/t

               P = (45.36 Kg)(9.8 m/s²)(2.44 m)/10 s

               P = 108.46 J/s

               P = 0.15 Horsepower
