She can jump high.
Literal
She [topic-は] high jump-up can.
跳び上がる ('to jump up, to leap upward') is a compound verb: 跳ぶ ('jump') + 上がる ('rise, go up'). The auxiliary 上がる adds the upward direction. 跳び上がれます is its polite potential form — 'is able to jump up.' The kanji 跳 specifically suggests a leap or bound, distinct from 飛ぶ ('fly'). Both verbs have similar pronunciation but different scope: 跳ぶ is for short bounds, 飛ぶ for flight. The adverbial 高く ('high') is the く-form of 高い.
