Ответ. Велосипедист, обладающий большой начальной скоростью, может, согласно закону сохранения энергии, подняться на некоторую высоту, не прилагая никаких усилий. При этом его кинетическая энергия перейдёт в потенциальную. Таким образом, приобретя кинетическую энергию на лёгком участке пути, он может потратить её для преодоления трудного.
