Homework Help: Work escalator question

  1. Apr 7, 2009 #1
    1. The problem statement, all variables and given/known data

    An escalator is 30.0 meters long and slants at relative to the horizontal. If it moves at 1.00 m/s, at what rate does it do work in lifting a 50.0-kg woman from the bottom to the top of the escalator

    im not to sure on how to go about doing this problem, the question doesnt make logical sense since its an escalator without an angle.... anyone have insight on this or am i just not seeing it.

    i no i didnt add anything except for the problem but any tips or help will push me off my feet because theres something i just dont see here

    i geuss you would use teh equation .5mv^2 +mgh=.5mv^2 + mgh which tehre is no H in this case so it would bsaically be a standard
    W=mg(hf-hi) which in this case would just be mg?
