A100 kg individual consumes 1200 kcal of food energy a day. calculate
(a) the altitude change, in m, if the food energy content was converted entirely into lifting the indi-
vidual under normal earth gravity.
(b) the velocity, in m/s, if the food energy content was converted entirely into accelerating the indi-
vidual from rest.
(c) the final temperature, in ◦c, of a 100 kg mass of liquid water initially at the normal human body
temperature and heated with the energy content of the food. you can use a liquid water specific
heat of 4.1 kj/kg k.
