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.

To calculate the work required to climb the flight of stairs, we need to use the formula:
Work = Force x Distance
In this case, the force exerted to climb the stairs is the weight of the firefighter. The weight can be calculated using the formula:
Weight = mass x gravity
The mass of the firefighter is given as 69.0 kg.
The acceleration due to gravity is approximately 9.8 m/s^2.
Using the weight formula, we have:
Weight = 69.0 kg x 9.8 m/s^2
Now we can calculate the force exerted by the firefighter.
Next, we need to determine the distance over which the force is applied. In this case, the distance is given as 22.0 m.
Finally, we can calculate the work using the formula mentioned earlier:
Work = Force x Distance
Substituting the values we have:
Work = Weight x Distance
Plug in the values we calculated:
Work = (69.0 kg x 9.8 m/s^2) x 22.0 m
Now, let's calculate the work required.
