Question

5. Lab Component:  (a) Find a flight of stairs somewhere near you.  Measure (ideally) the vertical height of the stairs.  If not possible... simply estimate the height (b) Walk up the stairs two times (1st time... slow), (2nd time... fast).   Measure & record the time for each ascent.  (c) Using your mass & the height of the stairs calculate the work required (in Joules & in calories) to climb the stairs.  This actually corresponds to calories ‘burned’.  Don’t be surprised if the calories ‘burned’ seems high... there is a good explanation (d) For both ascents, calculate the power generated in both of your ascents.  Calculate in Watts... reasonable results would anywhere from 100 Watts up to 1200 Watts
