Answer
By increasing the bicycle's kinetic energy as much as possible before the hill, the cyclist can reduce the amount of pedaling that is required while heading up the hill.
Work Step by Step
It is easier to pedal a bicycle on a level road so the cyclist tries to increase the kinetic energy of the bicycle by doing positive work on the bicycle by pedaling. As the bicycle goes up the hill, the bicycle's kinetic energy is gradually converted into potential energy. The cyclist can still make it up the hill by continuing to pedal, which does positive work on the bicycle.
By increasing the bicycle's kinetic energy as much as possible before the hill, the cyclist can reduce the amount of pedaling that is required while heading up the hill.
