each step is h.
(a) Determine the amount of chemical energy converted into mechanical energy by the traveler's leg muscles during
his escalator ride given that his mass is m. (Use any variable or symbol stated above along with the following as
necessary: g.)
energy =
(b) Determine the work the escalator motor does on this person. (Use any variable or symbol stated above along
with the following as necessary: g.)

Suppose a car travels 108 km at a speed of 30.0 m/s, and uses 2.0 gal of gasoline. Only 30 of the gasoline goes into useful work by the force that keeps the car moving at constant speed despite friction. (The energy content of gasoline is about 140 Mi/gal.) (a) What is the magnitude of the force exerted to keep the car moving at constant speed? (b) If the required force is directly proportional to speed, how many gallons will be used to drive 108 km at a speed of 28.0 m/s?
The force exerted by a diving board is conservative, provided the internal friction is negligible. Assuming friction is negligible, describe changes in the potential energy of a diving board as a swimmer drives from it, starting just before the swimmer steps on the board until just after his feet leave it.
