Part A: 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.
Part B:Calculate how much work is done by gravity, as she moves from the bottom to the top of the escalator.
Part C:Calculate how much work is done by the normal force on the woman’s feet, as she moves from the bottom to the top of the escalator.
Part D:
What is the total work done on the woman as she moves from the bottom to the top?
