How a Run-up Affects the Length of a Jump
A problem on gaining or losing ground of one-third braccio before a three-braccio leap
A short mechanics problem examines how a running start affects the length of a leap. A man clears three braccia from a fixed position; Leonardo asks how much of that distance he would lose if he drew back one-third of a braccio while executing the jump, and how much he would add if instead he advanced by one-third of a braccio. No diagram accompanies the problem, though faint offset marks show through from the adjacent leaves.

How a run-up changes the length of a jump
A leaper covers three braccia from one fixed position. The problem asks how much distance he loses if he recedes one-third of a braccio backward as he jumps, and how much he gains if instead he advances one-third of a braccio.
