Only about 20% of the Calories we consume are used for mechanical work (i.e., moving the body around). Estimate how many granola bars (150 Cal per bar) an 85 kg person will burn if they climb vertically up theside of the Empire State Building.
height of Empire State Building, h = 443 m
unit conversion: 1 Cal = 4184 Joules
The human body is not perfectly efficient. In fact, only
about 20% of the Calories we consume are used for
mechanical work (i.e., moving the body around).
Estimate how many granola bars (150 Cal per bar) an
85 kg person will burn if they climb vertically up the
side of the Empire State Building.
height of Empire State Building, h = 443 m
unit conversion: 1 Cal = 4184 Joules
A high jumper of mass 60kg consumes a meal of 3.00 x 10³ kcal prior to a jump. If 3.3% of
the energy from the food could be converted to gravitational potential energy in a single jump, how high could the athlete jump?
