The energy needed for a woman to climb a ladder is given by the change in potential energy she experiences. Defining the ground as being zero potential energy, her overall change in potential energy is
Ep = mgh
where Ep is the change potential energy, m is her mass, g is the gravitational acceleration (9.8m/s2 on earth) and h is the height she climbs.
Ep = (90kg)(9.8m/s2)(6m) = 5292kg*m2/s2 or 5292 Joules

The energy needed to climb a ladder can be calculated using the formula: potential energy = mass x gravity x height. Plugging in the values for the woman's mass (90 kg), height (6 meters), and the acceleration due to gravity (9.81 m/s^2), the energy required would be approximately 5294.2 Joules.
