A 50 kg woman steps onto an up-going escalator, which has an incline of 32° with respect to the horizontal and is moving at 0.5 m/s. The top of the escalator is 20 m above the ground level. Calculate how much work is done by the friction force between the woman's feet and the escalator step, as she moves from the bottom to the top of the escalator.
