Chapter 3, Problem 39P
. In the annual Empire State Building race, contestants run up 1,575 steps to a height of 1,050 ft. In 2003, Australian Paul Crake completed the race in a record time of 9 min and 33 S, Mr., Crake weighed 143 lb (65 kg)
,
(a) How much work did Mr., Crake do in reaching the top of the building?
(b) What was his average power output (in ft-lb/s and in hp)?
