    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
