In this problem, we are required to do some work using a given power.
Gravitational potential energy:
An elite Tour de France cyclist can maintain an output power of 470 W during a sustained climb. At this output power, how long would it take an 88 kg cyclist (including the mass of his bike) to climb the famed 1100-m-high Alpe d'Huez mountain stage? Neglect any friction.
