A 69.0 firefighter climbs a flight of stairs 22.0 high.


How much work is required?

    I assume you mean 69 kg
    and
    22 meters

    If so
    69*9.8 = 676 Newtons

    work = force * distance = 676*22 = 14,876 Joules

    You left the units off, which tells me you better pay more attention to the basics of this subject.
