When a frog jumps from a log, it pushes against the log with a force (action force) which propels it forward. Simultaneously, the log exerts an equal and opposite force (reaction force) back on the frog, enabling it to launch into the air. This is in accordance with Newton's third law of motion - for every action, there is an equal and opposite reaction.

The frog would never reach it because it only reaches halfway. Eventually the frog will reach a 'Planck Length'. Since you cannot halve a Planck Length, the frog will be stuck stationary on the log one planck length from the edge.
