A75 kg firefighter climbs a flight of stairs 28 m high how much work does he do?

The amount of work done by the firefighter is equal to 20,580‬ Joules.

Given the following data:

Scientific data:

To determine how much work is being done by the firefighter:

The work done by a body is simply the product of the perpendicular force acting on the body and the distance it covers.

Mathematically, work done is given by the formula:

    ......equation 1.

But,   ......equation 2.

Substituting eqn. 2 into eqn. 1, we have:

Work done = 20,580‬ Joules

20580 Joules of work is done by the firefighter.

Explanation:

Work done is defined as the force times distance travelled.

work=

Given:

mass= 75 kg

acceleration due to gravity =

h= height = 28 m

Putting in the values we get,

work=

Thus 20580 Joules of work is done by the firefighter.
