Answer #2

Work done is given by the equation,

W = Force × Displacement

= F × s

Here, the force acting on the woman is,

F =

where m is the mass of the woman,g is the acceleration due to gravity and is the inclination of the escalator.

Force acting on the woman,

  

Work done,

Here, s is the height = 65.1 m

= 15158 J
